1 September 1947: Captain Thomas Jefferson Wells, United States Army Air Forces, flew a Douglas C-54D-1-DC Skymaster, 42,72451, named Robert E. Lee ¹ by its Alabama-born pilot, from Wilmington Ohio, to Presque Isle, Maine, then on to Jacksonville, Florida, and finally, back to Wilmington. The flight covered approximately 2,901 miles (4,669 kilometers).

What was unusual, though, is that Captain Wells WAS NOT FLYING THE AIRPLANE!

Captain Wells’ Douglas C-54 flew itself from Clinton Army Air Field, Wilmington, Ohio, to Presque Isle AAF, on to Jacksonville AAF, then back to Wilmington. Following Great Circle courses, this was a total distance of 2,901 miles. (Great Circle Mapper)

Captain John J. Herbert, Jr., wrote about the flight in Flying Safety, a publication of the United States Air Force:

. . . No doubt you have followed, with some degree of amazement, the flight records of the Automatic C-54. A few of the longer hauls have been well over the 2,000 mile mark. For instance: 1 September 1947, Wilmington, Ohio to Presque Isle, Maine to Jacksonville, Florida to Wilmington, Ohio. A total of 2,900 miles. Except for the fact that the pilot, Capt. Thomas J. Wells, lined up on the takeoff runway, and manually pressed a button marked Wilmington, Ohio, every phase of the flight was automatic. Homing in on a landing beam is an element of automatic flight used only when the automatic C-54 desires to land. On  this 2,900-mile flight, the airplane flew to three destinations. The predetermined headings preset in the automatic controller directed the airplane to the first two destinations in turn, but the pre-selected landing sequence was set only for Clinton County.

There was no “remote control” over this airplane such as was used directing the “drones” used in the Bikini A-bomb tests. The Automatic Flight Controller, sometimes called the “Plane Brain” is entirely self-sufficient. Installed in the main cabin of the Automatic C-54, the brain stores information given to it before the flight begins, “reads” the flight and engine instruments, tunes and “listens” to beam signals, “computes” distances, time and airspeed and carries out the normal functions of the crew necessary to conduct a point-to-point flight.

The “Brain” retracts the gear when the airplane reaches 50 feet and retracts the flaps at 1,000 feet. The “brain” adjusts the power for continuous climb to cruising altitude. Navigation is done by two mileage counters and magnetic heading selectors. These instruments control the flight until the plane clicks off the preset number of miles on the present heading.

After the last mile has been clicked off, the airplane automatically homes on a predesignated radio station. When the airplane reaches “home,” throttles come back, props go forward, mixture goes full rich, wheels and flaps come down. The automatic C-54 then orbits the station, letting down at 500 feet per minute until it reaches 2,000 feet. At this time the airplane intercepts the glide path, makes a few corrections in azimuth, flies down the glide path and lands.

“Some touch-downs we have made, says Captain Wells, “could very easily have been classified as hard landings. But,” he adds, “that is the reason the C-54 was selected for this type of work. That gear can really take it.”

Another flight, which will take a front file in the archives of aviation history, began ast 1715 on the 21st of September 1947. With coloenl John M. Gillespie, Chief of the All-Weather Division in command, the automatic C-54 took off from Stephenville, Newfoundland on a transatlantic hop to Brize Norton, England. The elapsed time en route was 12 hours and five minutes. The distance 2,400 miles. Twelve sequences of the “no-hands” flight to England are shown in the accompanying illustration.

In summing up the future possibilities of automatic flight, let’s query Captain Wells, the man who pilots the pilotless airplane.

“We are strictly in the Model ‘T’ stage of development,” he says.

If a Model “T” can make it to England without the aid of a single human hand then I say, put us down for a ’48 model. We’ll buy it.”

Crewmembers for the transatlantic flight included T/Sgt Walter W. McKee, Wooster, OH, crew chief; James L. Anast, Columbus OH, chief of the automatic flight branch, Army All-Weather Flight Center; Captain Thomas J. Wells, Orlando, FL; T/Sgt Raymond  Centolella, Utica, NY, radio operator, and S/Sgt John C. Nimon, East Canton, OH, engineer. (AP Wirephoto via radio from London. Published in The Minneapolis Star, 23 September 1974, Page 13)

For the transatlantic flight, the airplane was under the command of Colonel James M. Gillespie. Captain Wells acted as copilot. The navigator was Captain Roman J. Whiting, with Captain Frank G. Shea as assistant navigator. Also on board were civilian James L. Anast, chief of the automatic flight branch, Army All-Weather Flight Center, George B. Johnson, project engineer. The crew chief was Technical Sergeant Walter W. McKee, with flight engineer Staff Sergeant John C. Nimon (Menon?), Technical Sergeant Raymond Centolella was the radio operator. Observers were Major Thomas F. Weldon, chief of the flying research section of the Air Materiel Command, Charles Franklin, communications and navigation branch, AMC; W.W. Downs, Sperry Gyroscope Company; Wing Commander T.R. Jeff and Group Captain H.E. Boster, Royal Air Force.

The airplane was 93 feet, 11 inches ( 28.626 meters) long with a wingspan of 117 feet, 6 inches (35.814 meters) and overall height of 27 feet, 5-5/16 inches (8.3645 meters). It was a low-wing monoplane with retractable tricycle landing gear. The wings had 7° dihedral. The total wing area was 1,462 square feet (135.8 square meters). It had an empty weight of  38,565 pounds (17,475 kilograms), and takeoff weight of 82,500 pounds (37,421 kilograms). With a crew of five, it could carry 49 troops.

The C-54D was powered by four air-cooled, supercharged Pratt & Whitney Twin Wasp R-2000-11 two-row, fourteen-cylinder radial engines with a compression ratio of 6.52:1. The engine required 100/130 octane aviation gasoline. The R-2000-11 drove three bladed Hamilton Standard Hydromatic propellers with a diameter of 13 feet, 1 inch (3.988 meters) through a 2:1 gear reduction. This engine had a Normal Power rating of 1,100 horsepower at 2,550 r.p.m. at 7,500 feet (2,286 meters), and 1,000 horsepower at 2,550 r.p.m. at 17,000 feet (5,182 meters); Military Power, 1,350 horsepower at 2,700 r.p.m. at 3,000 feet (914 meters) and 16,000 feet (4,877 meters); Takeoff power, 1,350 horsepower at 2,700 r.p.m. (1,450 horsepower if the engine  incorporated plain main bearings). The R-2000-11 was 49.10 inches (1.247 meters) in diameter, 59.62 inches (1.514 meters) long, and weighed 1,562 pounds (708.5 kilograms). The engine was sold commercially as the Twin Wasp 2SD11-G.

The C-54 had a maximum speed 267 knots (307 miles per hour/494 kilometers per hour) at 18,300 feet (5,578 meters), and maximum ceiling of 28,000 feet (8,534 meters). With a fuel capacity of 2,662 gallons (10,077 liters), its maximum  range was 1,650 nautical miles (1,899 statute miles/3,056 kilometers).

Douglas built 515 C-54s at Clover Field (manufacturer code -DO) and 655 at Douglas Field, near Chicago, Illinois (manufacturer code -DC). 388 of these were the C-54D variant. The C-54 was produced commercially as the Douglas DC-4.

42-72451 (MSN 10556 was transferred to the United States Coast Guard, and retired to “The Boneyard” at Davis-Monthan AFB, Tucson, Arizona, 5 May 1964.

1 September 1946: Just one year after World War II came to an end, the National Air Races returned to Cleveland, Ohio. Grandstands were set up at the site of the Fisher Body Aircraft Plant No. 2, where assemblies for B-25 and B-29 bombers had been produced.

The Thompson Trophy Race was one of the most popular events because it was in view of the crowds. Sponsored by Thompson Products Company (the predecessor of TRW), it was a ten-lap pylon race flown at low altitude around a 30-mile (48.3 kilometers) course. There were two divisions. The R Division was for airplanes with reciprocating engines, and the J Division was for turbojet powered airplanes.

The race course was laid out as a parallelogram, with two 10-mile (16.1 kilometer) sides, and two 5-mile (8.0 kilometer) sides. There were two 75° turns and two 105° turns.

In addition to the Thompson Trophy, the race winner would receive $20,000 in prize money (about $342,400 in 2018 U.S. dollars). There were additional $2,000 prizes for the leader of each lap. A pilot who set a speed record during the race would win the Allegheny-Ludlum Trophy and $2,000.

Entrants for the 1946 race included many well-known air racers, test pilots and combat pilots. They included Cook Cleland, a U.S. Navy dive bomber pilot and test pilot; Woodrow W. (“Woody”) Edmondson, an aerobatic pilot; Howard Clifton (“Tick”) Lilly, a test pilot for the National Advisory Committee for Aeronautics (NACA, predecessor of NASA); Alvin Melvin (“Tex”) Johnston, an experimental test pilot with the Bell Aircraft Corporation; Anthony W. (“Tony”) LeVier, Chief Engineering Test Pilot for the Lockheed Aircraft Corporation, and an experienced pylon racer; Earl Hill Ortman, test pilot for Douglas Aircraft Company, and also an experienced racer; Howard L. Pemberton; Bruce Raymond; Robert Swanson; Charles (“Chuck”) Tucker, who had flown P-40s with the “Flying Tigers” in China, and an Army Air Corps test pilot; George Schwarz Welch, the Army Air Corps hero of Pearl Harbor, and test pilot for North American Aviation, Inc.; and Sylvester Joseph (“Steve”) Wittman, an aircraft designer and air racer.

Before the war, the races used specially-constructed racing aircraft and production civil aircraft. Following the war, the expense of developing a purpose-built, competitive air racer was no longer feasible, so surplus military fighters were used.

Of the twelve airplanes competing in the 1946 Thompson Race, there was one Bell Aircraft Corporation P-39Q Airacobra; four Bell P-63 Kingcobras; one Goodyear Aircraft Corporation FG-1D Corsair (a licensed variant of the Vought-Sikorsky F4U Corsair); a Lockheed Aircraft Corporation P-38L Lightning; and five North American Aviation, Inc., P-51D Mustangs.

Jack Woolams, Chief Test Pilot for Bell Aircraft Corporation, Experimental Test Pilot Tex Johnston, and Bell’s Chief Engineer, Robert Morris Stanley, had determined that a properly prepared Bell P-39 Airacobra could outrun and outfly a North American Aviation P-51 Mustang in the Thompson race.

A Bell Aircraft mechanic was sent to inspect surplus P-39s in storage at Ponca City, Oklahoma. He selected two nearly-new P-39Q Airacobras, each with less than 50 hours flight time. Woolams and Johnston paid $3,000 for the two fighters and they were flown back to the Bell plant at Buffalo, New York.

Jack Woolams’ Cobra I was a P-39Q-10-BE, U.S. Army Air Corps serial number 42-20733. Tex Johnston’s Cobra II was also a P-39Q-10-BE, 42-20869 (Bell serial number 26E-324).

The Bell P-39 Airacobra was a single-engine, single-place low-wing monoplane with retractable tricycle landing gear. An Allison V-1710 V-12 engine was mounted behind the cockpit in an unusual mid-engine configuration, with a drive shaft passing under the cockpit floor and turning the propeller through a remotely-mounted 1.8:1 gear reduction unit. This allowed the fighter to be armed with a large 37 mm autocannon which fired through the propeller hub.

The P-39Q was the final production version of the Airacobra. It was 30 feet, 2 inches (9.195 meters) long with a wingspan of 34 feet, 0 inches (10.363 meters) overall height of 12 feet, 5 inches (3.785 meters). The wings’ angle of incidence was +2° and there was 4° 0′ dihedral. The total wing area was 213 square feet (19.78 square meters). The horizontal stabilizer had +2° 15′ incidence and no dihedral.   The P-39Q had an empty weight of 5,692 pounds (2,704 kilograms), and maximum gross weight of 8,350 pounds (3,787 kilograms).

The production P-39Q was powered by a liquid-cooled, supercharged, 1,710.597-cubic-inch-displacement (28.032 liter) Allison Engineering Company V-1710-E19 (V-1710-85) single overhead camshaft (SOHC) 60° V-12 engine with four valves per cylinder and a compression ratio of 6.65:1. The V-1710-85 had a continuous power rating of 810 horsepower at 2,600 r.p.m. at Sea Level, and 1,000 horsepower at 2,600 r.p.m. at 14,000 feet (4,267 meters). The engine’s takeoff power rating was 1,200 horsepower at 3,000 r.p.m., and its military power rating was 1,125 horsepower at 3,000 r.p.m., at 14,600 feet (4,450 meters). 100/130 octane aviation gasoline was required. The Allison drove a three-bladed Aeroproducts Division A632S-C1 hydraulically-operated constant-speed propeller with a diameter of 11 feet, 7 inches (3.531 meters) through a 2.23:1 gear reduction. The V-1710-85 was 16 feet, 2.00 inches (4.928 meters) long, 3 feet, 1.56 inches (0.954 meters) high, and 2 feet, 5.28 inches (0.744 meters) wide. It weighed 1,435 pounds (651 kilograms).

The Bell P39Q-10-BE had a maximum speed of 385.0 mph (619.6 kilometers per hour) at 11,000 feet (3,353 meters). Its service ceiling was 34,300 feet (10,455 meters), absolute ceiling, 35,700 feet (10,881 meters), and its range was 1,075 miles (1,730 kilometers).

The P-39Q was armed with one Browning M4 37 mm autocannon with 30 rounds of explosive ammunition, and four Browning AN-M2 .50-caliber machine guns, with two in the nose with 200 rounds per gun, and one mounted under each wing in pods with 300 rounds per gun. The M4 cannon fired a 1.34 pound (608 grams) high-explosive shell at 2,000 feet per second (610 meters per second). The gun had a rate of fire of 150 rounds per minute.

The Bell Aircraft Corporation built 9,558 P-39s. 4,905 of these were P-39Qs. 705 were the P-39Q-10-BE variant.

Bell Aircraft provided hangar space for the two Airacobras, and assigned an engineer and five mechanics to the project. Cobra I was painted red with black accents. It was issued Civil Aeronautics Administration experimental registration NX92847. Its race number, 75, was painted on the wings and fuselage. Cobra II was painted yellow with black trim, and registered NX92848. Its race number was 84.

Both airplanes were stripped of armament, armor and self-sealing fuel tanks. The landing gear was modified to reduce its retraction time from 22 seconds to just 4 seconds. The standard fabric-covered ailerons, rudder and elevators were covered with sheet aluminum. Adjustable trim tabs were deleted. Gyroscopic instruments were removed. The pitot tube was moved from the left wing tip and placed on a long boom projecting through the propeller hub. Thin, light-weight Goodyear fuel bladders were installed, not only reducing weight, but increasing the Airacobras’ fuel capacity by 10%. The roll-down side windows of the P-39 were replaced by fixed Plexiglas panels.

Engineers at Allison recommended that a modified Allison XV-1710-135 (E31) engine be used for the two racers. The modified engines used an increased-diameter supercharger impeller and undersized pistons to reduce cylinder wall friction. Using 140-octane Mobil aviation gasoline, they produced 2,000 horsepower at 3,200 r.p.m. with 86 inches (291 kilopascals) of manifold pressure. The high power output required that the engine be provided with a continuous injection of a precisely-measured water and ethyl/methyl alcohol solution when operating above 57 inches (193 kilopascals) of manifold pressure. An 85 gallon (322 liter) tank for the injection mixture was placed in the nose.

The increased power of the modified XV-1710-135 required that the P-39’s standard three-bladed propeller be replaced by a four-bladed unit from the P-63 Kingcobra. This was an Aeroproducts A624S constant-speed propeller with hollow steel blades. Its diameter was 11 feet, 0 inches (3.531 meters). The propeller gear reduction ratio remained the same, at 2.23:1, as did the remote gear box, at 1.8:1.

The V-1710-E31 was longer and heavier than the -E19 because of an outboard reduction gear box. It was 17 feet, 4.00 inches (5.283 meters) long, 3 feet, 0.75 inches (0.933 meters) high, with the same 2 foot, 5.28 inch (0.744 meters) width. It weighed 1,500 pounds (680 kilograms).

When race qualifications were held, Tex Johnston was placed first with his yellow Cobra II. His average speed was 409.091 mph (658.368 kilometers per hour). George Welch was second with his P-51D, number 37. Jack Woolams and Cobra I were third.

Jack Valentine Woolams was killed on 30 August, two days before the race, when his Cobra I crashed into Lake Ontario while returning to the Bell plant for an engine change. The Airacobra’s windshield may have collapsed at over 400 miles per hour (644 kilometers per hour).

The Thompson Trophy Race was held on Sunday, 1 September 1946. Tex Johnston, leading the field, took off and retracted his landing gear, climbing to 300 feet (91 meters). As he approached the first turn, he rolled Cobra II into a 4G turn (75.5° angle of bank) and dove to 60 feet (18 meters). As he made the turn, he was already pulling far ahead of the other racers.

George Welch dropped out when his Merlin engine began overheating. Tony LeVier’s P-38 Lightning, race number 3, held on to second place. By the ninth lap, Tex Johnston was passing the airplanes at the back of the field.

On the final turn, Johnston rolled into a 90° bank, and at only 50 feet (15 meters) above the ground, passed inside a Bell P-63 Kingcobra at 430 miles per hour (692 kilometers per hour) to win the race. His average speed for the ten laps was 373.908 mph (601.746 kilometers per hour).

Tony LeVier and his Lightning were in second place at 370.193 mph (595.768 kilometers per hour). Finishers 3, 4 and 5 were P-51D Mustangs. Number 6 was the lone FG-1D Corsair, followed by another P-51D. Proving that Woolams, Johnston and Stanley knew their airplane, the final three finishers were the three remaining P-63 Kingcobras.

Cobra II competed in the 1947 Thompson Trophy Race. Flown by Bell Aircraft Corp. test pilot Gerald A. (“Jay”) Demming, and carrying the race number 11, it finished in third place behind two Goodyear F2G-1 Super Corsairs. Demming’s average speed was 367.625 miles per hour (591.635 kilometers per hour).

In the 1948 Thompson race, Cobra II, still carrying the number 11, was flown by Charles Brown. For this year, the race was twenty laps of a shorter, 15 mile (24.1 kilometer) course. Cobra II had qualified in first place with an average speed of 418.300 miles per hour (673.189 kilometers per hour). Brown led the race for 18 laps. His highest speed for a single lap was 413.907 miles per hour (666.119 kilometers per hour). He had to land, though, when the modified Allison engine began losing power. The race was won by a P-51D Mustang.

The history of Cobra II is elusive until it was purchased by Ed Maloney in 1960. It was sold to Michael D. Carroll in 1967. Carroll was the owner of Signal Trucking Co., and lived in Palos Verdes, California. The Airacobra was now registered N9824. Carroll had the airplane’s wings shortened by 4 feet per side (1.2 meters), and renamed it Cobra III.

On 10 August 1968, Carroll and Cobra III took of from Long Beach Airport (LGB), enroute to Orange County Airport (SNA), at nearby Santa Ana, California. At 11:15 a.m., the racer crashed at the Seal Beach Naval Weapons Station. Carroll bailed out, but his parachute did not open and he was killed. His body was located 125 feet (38 meters) from the wreckage. There was no post-crash fire. Lieutenant Commander Jack Kellicott, U.S. Navy, said that the airplane had run out of fuel.

Tex Johnston left Bell Aircraft Corporation and moved on to Boeing in Seattle, initially testing the swept-wing XB-47 Stratojet. He made the first flights of the YB-52 and XB-52 Stratofortress; the Model 367-80 (the “Dash 80”), which he notoriously rolled over Lake Washington, 6 August 1955; the KC-135A Stratotanker; and the Model 707 airliner. As Boeing’s Chief of Flight Test, Tex Johnston set the standard by which modern flight testing is carried out.

Three waves of Junkers Ju 87 B Stuka dive bombers from Sturzkampfgeschwader 76 and Sturzkampfgeschwader 2 Immelman attacked the defenseless town and dropped 46,000 kilograms (101,413 pounds) of 500 and 50 kilogram bombs.

The first target was the Szpital Wszystkich Świętych (All Saints Hospital), which was marked with red crosses. 26 patients and 6 nurses were killed.

In just over one hour, 75% of the town was destroyed and more than 1,200 people were killed. The death rate was twice that of the infamous attack on the Spanish town of Guernica by the Nazi Condor Legion during the Spanish Civil War.

By the time the war ended six years later, over 78,000,000 people had died.

1 September 1938: Jackie Cochran departed the Union Air Terminal, Burbank, California, at 3:00 a.m., flying her Seversky AP-7, NX1384, c/n 145. Her destination was Cleveland, Ohio, the finish line for the Bendix Trophy Race, 2,042 miles (3,286 kilometers) away.

NX1384 was built by the Seversky Aircraft Corporation of Farmingdale, Long Island, New York, especially for Jackie Cochran. It had been flown from the factory to Burbank by Major Alexander Nikolaievich Prokofiev de Seversky just two days earlier. His flight set an East-to-West Transcontinental Speed Record of 10 hours, 2 minutes, 55.7 seconds.

The AP-7 racer was an improved version of Major de Seversky’s P-35A fighter, which was the U.S. Army Air Corps’ first all-metal single-engine airplane with an enclosed cockpit and retractable landing gear.

Cochran’s AP-7 was powered by an air-cooled, supercharged, 1,829.39-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S1B3-G (R-1830-11) two-row 14-cylinder radial engine rated at 850 horsepower at 2,450 r.p.m. at 5,000 feet (1,524 meters), and 1,000 horsepower at 2,600 r.p.m. for take off. The engine turned a three-bladed Hamilton-Standard controllable-pitch propeller through a 3:2 gear reduction. The R-1830-11 was 4 feet, 8.66 inches (1.439 meters) long with a diameter of 4 feet, 0.00 inches (1.219 meters), and weighed 1,320 pounds (599 kilograms).

“Finally the P-35 arrived. I decided that I didn’t want to take it into the air for a test even if I could. The racing officials impounded it because it was a prototype and there was some kind of rule about untested planes. I would test it en route. . . Finally, I got to sit in the cockpit. I began to study all the instruments by the hour. I can almost see them still.

“There are about a hundred or more buttons, levers, and other gadgets to push, pull or twirl. . .  I close my eyes and reach for everything in the dark. And I keep at this until I can get to them blindfolded and with no false moves. . . 

“I finally see Cleveland. . . (a)nd am going so fast that I pass the airport and come in from the wrong side. . . Have I won? The crowds are cheering. It’s a standing ovation. . . I have won the Bendix.”

“I often wonder what is meant exactly by a considered risk. . . In my case I never could ponder over the risks too much because I had to take a fast plane whenever it became available to me and make the best of it. I won the 1938 Bendix Race in a Seversky pursuit plane which I had never flown until that night, when, with a heavy overload of gas, I took off in the race. The plane was delivered from the factory to me just two days before the race and under the rules it had to be immediately impounded. It was a prototype that had not yest been tested. I tested it en route during the race. Its feature was that it had wings that were in effect integrated tanks so that most of the wings could be filled with fuel, thus adding range. It developed in flight that the fuel from the right wing would not properly feed the engine. By force on the stick I had to hold that wing much higher than the other from time to time in order to drain the fuel from that right wing into the left wing and from the left wing into the engine. When I got the plane back to the factory after the race a large wad of wrapping paper was discovered near the outlet of the right-wing tank. No wonder the drainage had been bad. How, for example, could that risk be properly considered i advance? The paper in the tank could have been sabotage. Some thought so at the time. More likely it was paper pasted on the inside of the wing during manufacture which had not been removed and which worked loose from the action of the gasoline and the vibration of the plane.”

Jackie Cochran was the third pilot to leave Burbank, but the first to arrive at Cleveland. Her elapsed time for the flight from California to Ohio was 8 hours, 10 minutes, 31.4 seconds, for an average speed of 249.774 miles per hour (401.895 kilometers per hour). For her first place finish, Ms. Cochran won a prize of $12,500.

After being congratulated on her win by Vincent Bendix and other race officials, Cochran had her Seversky monoplane refueled. She then got back in to its cockpit and took off for Floyd Bennett Field, new York. She landed there 10 hours, 12 minutes, 55 seconds after leaving Burbank. This was a new West-to East Transcontinental Speed Record.
