12 April  1918: Allan and Malcolm Loughead, owners of the Loughead Aircraft Manufacturing Company of Santa Barbara, California, set speed and distance records as they flew their twin-engine, ten-place F-1 flying boat from Santa Barbara to San Diego. The F-1 traveled 211 miles (340 kilometers) in 3 hours, 1 minute.¹

The F-1 took off from the waters off West Beach at Santa Barbara at 9:21 a.m., passed Point Fermin at 10:40 a.m., Oceanside at 11:55 a.m., and arrived at North Island at 12:23 p.m.² The airplane was flown by the two Loughead Brothers and carried two passengers.

GREAT SEAPLANE MAKES RECORD ON FLIGHT

     SAN DIEGO, April 12.—The big seaplane F-1, piloted by Malcolm Loughead and carrying three passengers, arrived here at 12:23 this afternoon.

     The F-1 left Santa Barbara at 9:21 this morning and the estimated distance of 190 miles between that city and San Diego was therefore covered in exactly three hours and two minutes, a speed of approximately 63 1-3 miles an hour. The big seaplane was first sighted over Point Loma and within a few minutes alighted on the surface of San Diego Bay a short distance from the United States army aviation station at North Island. At 12:23 the seaplane reached the North Island landing and was hauled ashore by army men in waiting. According to Pilot Loughead, the trip was made without incident, although during the latter part of the trip headwinds were met with which retarded the speed of the aircraft.

————

     Three hours and two minutes by air flight to San Diego from Santa Barbara—that’s the record established today by Allan and Malcolm Loughead, in their big hydroplane, F-1, carrying as passengers Alfred Holt and Carl Christopherson, employees of the Loughead Aeroplane Manufacturing Company.

     The distance of 190 miles, by airplane, was made without mishap. The start from Santa Barbara gathered quite a group of citizens, among them being a number of stockholders in the Loughead company, and thousands would have been there to witness the notable start had it been known at what hour the flight would start.

     During the morning the Lougheads received a dispatch from government officials at the aviation headquarters on North Island, San Diego, informing them that air and ocean conditions were perfect all the way south, and asking that the flight be made today.

     The Lougheads were even at that moment getting ready for the departure, and arrangements were hastened. The bay was ruffled by a breeze, and the combers sparkled in the warm sunlight, as the hydroplane motors were started, and the big fans began to whirr. There were hasty farewells, and every man waved his hat and every woman present shook a kerchief, while the cheers broke forth from all as the big plane sped down the ways, and went skidding into the sea.

     At the wheels were Allan and Malcolm Loughead, while Christopherson and Holt occupied places in the passengers’ quarters at the head of the big plane. The machine was guided in a half circle, taking a southwesterly course at first, until beyond the pleasure pier, where it rose from the bosom of the sea, and rapidly ascended to an altitude of about 500 feet, when it took a southeasterly course, and heading down the channel toward Oxnard.

     It was a perfect get-away, and no bird ever took to the air more gracefully than the big plane rose above the sea and soared away, easily, the very hypothesis of graceful motion, and the speed at which it was travelling soon took it out of sight to the south.

     From Ventura and Hueneme the flight was witnessed by a large number of citizens, and at Point Fermin, near San Pedro, the passing of the plane attracted great interest. In fact, all the way south, great crowds watched eagerly and it was a continuous ovation that greeted the airmen from the land.

     At San Diego the fliers were met by a big crowd, and their stay in the southern city is being made one prolonged reception. From many points along the coast today telephone and telegraph messages have flashed, reporting the passing of the machine, whose eventful trip is the biggest sensation of the day in aviation circles.

     It is stated that the flight establishes a long distance record for a passenger-carrying hydroplane. The plane will be tested out by the government aviation officials, and it is expected that within a very few days the announcement will be made of a contract awarded the Loughead Brothers by the government for other machines.

     Experts who have examined the F-1 state that it is perfectly built, and the finest machine of its class afloat.

Loughead Aircraft Manufacturing Company F-1. (Lockheed Martin).

Designed by friend and employee John Knudson (“Jack”) Northrop, and built in a garage on State Street, the F-1 was launched on a wooden ramp at West Beach.

The airplane was intended for the U.S. Navy, but the end of World War I ended the requirement for new airplanes.

The Loughead F-1 was a twin-engine, three-bay biplane flying boat operated by a crew of 2. It could carry 8–10 passengers. The airplane was 35 feet (10.668 meters) long. The span of the upper wing was 74 feet (22.555 meters) and the lower wing was 47 feet (14.326 meters). The height was 12 feet (3.658 meters). The F-1 had an empty weight of 4,200 pounds (1,905 kilograms) and gross weight of 7,300 pounds (3,311 kilograms).

The F-1 was powered by two right-hand tractor, water-cooled, normally-aspirated 909.22-cubic-inch-displacement (14.899 liters) Hall-Scott A-5-engines. These were inline six-cylinder single-overhead-camshaft (SOHC) engines with a compression ratio of 4.6:1. It was rated at 150 horsepower and produced 165 horsepower at 1,475 r.p.m. The engines were mounted on steel struts between the upper and lower wings. The engines were direct-drive and turned two-bladed, fixed pitch propellers with a diameter of 8 feet, 8 inches (2.642 meters). The Hall-Scott A-5-a was 5 feet, 2.5 inches (1.588 meters) long, 2 feet, 0 inches (0.610 meters) wide and 3 feet, 7.875 inches (1.114 meters) high. It weighed 595 pounds (270 kilograms).

The F-1 had a cruise speed of 70 miles per hour (113 kilometers per hour) and maximum speed of 84 miles per hour (135 kilometers per hour).

The F-1 was converted to a land plane with tricycle undercarriage and redesignated F-1A. During an attempted transcontinental flight, it twice suffered engine failure and was damaged. Reconfigured as a flying boat, the airplane was used for sight-seeing before being sold. It was abandoned on a beach at Santa Catalina Island, off the coast of Southern California, and was eventually destroyed.

The Loughead Aircraft Manufacturing Company would go on to become one of the world’s leading aerospace corporations.

¹ The certifying source for this “record” is not known. The distance flown and elapsed time for the flight cited here are from Wikipedia. The Great Circle distance from today’s Santa Barbara Airport (SBA) to NAS North Island (NZY) is 193 statute miles (311 kilometers). However, contemporary news reports suggest that the Loughead brothers flew the F-1 along California’s southern coastline, rather than making a direct flight across the Santa Barbara Channel, Santa Monica Bay, the Catalina Channel, and on to San Diego Bay. At the time of this flight, the governing body for aviation in the United States was the Aero Club of America, while official flight records were certified by the Fédération Aéronautique Internationale, which was based in France. The ACA ceased to exist in 1923, replaced by today’s National Aeronautic Association. The FAI online records database list only two world records set in 1918, both altitude records set by Major Rudolph Schroeder, 18 September 1918, at Dayton, Ohio.

² The Los Angeles Times, the Oakland Tribune and the San Bernardino Daily Sun state that the time of the takeoff was 9:23 a.m. The Tribune cites the arrival time as 12:24 p.m., while the Daily Sun reported the time as both 12:32 and 12:24. Various newspapers reported the distance flown by the F-1 as 190 miles (306 kilometers), while The Salt Lake Herald-Republican-Telegram printed that it was 200 miles (322 kilometers).

Medal of Honor, Airman 1st Class William Hart Pitsenbarger, United States Air Force

Airman 1st Class William Hart Pitsenbarger, United States Air Force

The President of the United States of America, authorized by Act of Congress, March 3, 1863 has awarded in the name of the Congress the Medal of Honor posthumously to:

A1C WILLIAM H. PITSENBARGER
UNITED STATES AIR FORCE
for conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty Near Cam My, 11 April 1966:

Rank and organization: Airman First Class, U.S. Air Force, Detachment 6, 38th Aerospace Rescue and Recovery Squadron, Bien Hoa Air Base, Republic of Vietnam.

Place and date: Near Cam My, 11 April 1966

Entered service at: Piqua, Ohio

Born: 8 July 1944, Piqua, Ohio

Citation: Airman First Class Pitsenbarger distinguished himself by extreme valor on 11 April 1966 near Cam My, Republic of Vietnam, while assigned as a Pararescue Crew Member, Detachment 6, 38th Aerospace Rescue and Recovery Squadron. On that date, Airman Pitsenbarger was aboard a rescue helicopter responding to a call for evacuation of casualties incurred in an on-going firefight between elements of the United States Army’s 1st Infantry Division and a sizable enemy force approximately 35 miles east of Saigon. With complete disregard for personal safety, Airman Pitsenbarger volunteered to ride a hoist more than one hundred feet through the jungle, to the ground. On the ground, he organized and coordinated rescue efforts, cared for the wounded, prepared casualties for evacuation, and insured that the recovery operation continued in a smooth and orderly fashion. Through his personal efforts, the evacuation of the wounded was greatly expedited. As each of the nine casualties evacuated that day were recovered, Pitsenbarger refused evacuation in order to get one more wounded soldier to safety. After several pick-ups, one of the two rescue helicopters involved in the evacuation was struck by heavy enemy ground fire and was forced to leave the scene for an emergency landing. Airman Pitsenbarger stayed behind, on the ground, to perform medical duties. Shortly thereafter, the area came under sniper and mortar fire. During a subsequent attempt to evacuate the site, American forces came under heavy assault by a large Viet Cong force. When the enemy launched the assault, the evacuation was called off and Airman Pitsenbarger took up arms with the besieged infantrymen. He courageously resisted the enemy, braving intense gunfire to gather and distribute vital ammunition to American defenders. As the battle raged on, he repeatedly exposed himself to enemy fire to care for the wounded, pull them out of the line of fire, and return fire whenever he could, during which time, he was wounded three times. Despite his wounds, he valiantly fought on, simultaneously treating as many wounded as possible. In the vicious fighting which followed, the American forces suffered 80 percent casualties as their perimeter was breached, and airman Pitsenbarger was finally fatally wounded. Airman Pitsenbarger exposed himself to almost certain death by staying on the ground, and perished while saving the lives of wounded infantrymen. His bravery and determination exemplify the highest professional standards and traditions of military service and reflect great credit upon himself, his unit, and the United States Air Force.

11 April 1952: At the Piasecki Helicopter Corporation factory at Morton Grove, Pennsylvania, the first YH-21 tandem-rotor helicopter, serial number 50-1231, made it’s first flight. The test pilots were Leonard Joseph (“Len”) LaVassar and Martin P. (“Marty”) Johnson, both former U.S. Navy aviators.

The Piasecki Helicopter Corporation built 18 pre-production YH-21-PH helicopters, followed by three production variants, the H-21A, H-21B and H-21C.

The U.S. Air Force immediately ordered 32 H-21A helicopters for Search and Rescue operations. The Workhorse was well suited to cold weather operations and it was widely used in Alaska, Canada, and the Antarctic. Another 163 H-21B models were ordered as a troop transports. The U.S. Army ordered a similar H-21C variant.

The YH-21 was a single-engine, tandem-rotor transport helicopter. It was normally operated by two pilots, with a flight mechanic (crew chief), and could carry up to 20 soldiers under ideal conditions.

With rotors turning, the YH-21’s overall length was 86 feet, 5 inches (26.340 meters). The fuselage was 52 feet, 6 inches (16.002 meters) long, and the helicopter had an overall height of 16 feet, 0 inches (4.877 meters). The rotors were 44 feet, 0 inches (13.411 meters) in diameter. The YH-21’s empty weight was approximately 8,117 pounds (3,682 kilograms) and maximum gross weight was 14,500 pounds (6,577 kilograms).

The forward rotor turned counter-clockwise, as seen from above. (The advancing blade is on the helicopter’s right side.) The rear rotor turns the opposite direction. Normal operating speed for the main rotors was 233 to 258 r.p.m. (233–270 r.p.m. in autorotation.) The counter-rotating rotors cancelled out engine torque, eliminating any need for a tail rotor. The angle in the fuselage was intended to provide adequate vertical clearance between the intermeshing fore and aft rotor assemblies. (Later tandem rotor helicopters use raised pylons.)

The H-21 was powered by a single air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.875 liter) Wright Aeronautical Division Cyclone 9 863C9WD1 (R-1820-103) nine-cylinder radial, mounted inside the fuselage at midship, and drove the front and rear rotors in opposite directions through drive shafts and gear boxes. The Wright R-1820-103 engine was rated at 1,275 horsepower at 2,500 r.p.m., and 1,425 horsepower at 2,700 r.p.m., for takeoff. This direct-drive engine had a compression ratio of 6.80:1 and required 100/130 aviation gasoline. The engine was 4 feet, 0.50 inches (1.232 meters) long, 4 feet, 6.95 inches (1.396 meters) in diameter, and weighed 1,350 pounds (612 kilograms). Wright built 971 R-1820-103s from November 1950 through 1957.

The YH-21 could reach a maximum speed in level flight of 131 knots (151 miles per hour/243 kilometers per hour). Its Never Exceed limit (VNE) was 151 knots (174 miles per hour /280 kilometers per hour) (diving). The maximum Sea Level range was 397 nautical miles (457 statute miles/735 kilometers) at 125 knots (144 miles per hour/232 kilometers per hour). Its service ceiling was 19,200 feet (5,852 meters).

In 1955, Piasecki became Vertol and eventually Boeing Vertol. The company would continue to produce tandem rotor helicopters such as the H-46 Sea Knight and the CH-47 Chinook, which is still in production.

Lt. Merritt Duane Francies (left) and Lt. William S. Martin with a Piper L-4J Grasshopper, 44-80699 (54 ☆ G) (Passion Aviation)

11 April 1945: 1st Lieutenant Merritt Duane Francies, Field Artillery, USA, and forward observer Lieutenant William S. Martin, 71st Armored Field Artillery Battalion, 5th Armored Division, were flying a Piper L-4H Grasshopper on a reconnaissance mission near Dannenberg, Germany. This was Francies’ 142nd combat mission.

The Grasshopper (Piper Model J3C-65D) was named Miss Me!? Its U.S. Army serial number was 43-29905, and it was marked 54 ☆ J.

The two airmen saw an enemy Fieseler Fi 156 Storch flying beneath them. The Storch was similar to the Grasshopper. Both were single engine, high-wing monoplanes with fixed landing gear. The Storch was larger and faster, but both airplanes had similar missions during the War.

Francies put his L-4H into a dive and overtook the Luftwaffe airplane. Both American officers carried M1911 .45-caliber semi-automatic pistols, with which they fired on the Fieseler. Both officers emptied the 7-round magazines, then reloaded. The enemy airplane began to circle.

Lieutenant Francies approached again, coming to within an estimated 30 feet (9 meters) of the German airplane. Both opened fire again, striking the Storch in the windshield and in a fuel tank. It went into a spin, then crashed. Francies landed his airplane nearby.

The two German crewmen got out of the wrecked Fi 156 and tried to run, but the observer had been wounded in the foot. Lieutenant Martin fired a warning shot and the German pilot stopped, then surrendered.

The captured airmen were turned over to an American tank crew. Francies later said, “I never found out their names. They could have been important, for all I know. We turned them over to our tankers about 15 minutes later after the injured man thanked me many times for bandaging his foot. I think they thought we would shoot them.”

Duane Francies, Freshman, (The Cascade 1940)

Merritt Duane Francies was born 21 July 1921. He was the son of Merritt Charles Francies, a fruit farmer, and Kathleen I. Horan Francies. He studied at Seattle Pacific College for one year before he enlisted as private, Air Corps, United States Army, 10 December 1941, at Spokane, Washington. Private Francies was 5 feet, 10 inches (1.78 meters) tall and weighed 170 pounds (77 kilograms).

2nd Lieutenant Francies had trained as a pilot and was assigned to an L-4 light observation airplane to conduct reconnaissance for the 5th Armored Division. On 19 September 1944 he rescued a wounded forward observer, for which he was awarded the Bronze Star. He was awarded an Air Medal on 27 September 1944. Francies received a battlefield promotion to 1st lieutenant, 15 January 1945.

Following the air-to-air battle with the Storch, Lieutenant Francies was recommended for the Distinguished Flying Cross, 24 April 1945. Major General Walter Jensen, 14th Army Corps, present the medal to him 22 years later, 13 March 1967.

Duane Francies married Miss Jo Ann Hulson in Lake County, Indiana, 29 March 1947. He died at Chelan, Washington, 5 May 2004.

The Piper L-4H Grasshopper is a single-engine, two-place strut-braced high-wing monoplane based on the civilian Piper J-3C Cub. In military service, it was used as a short-range reconnaissance and liaison aircraft. The cockpit had a tandem configuration. The airplane was constructed of a welded steel tube fuselage, and the wings had wooden spars and riveted aluminum ribs. It was covered with doped fabric.

The L-4H was 22 feet, 4½ inches (6.820 meters) long, with a wingspan of 35 feet, 2½ inches (10.732 meters). Its height, when parked in 3-point attitude, was 8 feet, 6 inches (2.591 meters) to the top of the propeller arc. The wing has a chord of 5 feet, 3 inches (1.600 meters) and a total area of square feet ( square meters). It has an angle of incidence of 1° 37′ and 0° 41′ negative twist. The variable incidence horizontal stabilizer has a span of 9 feet, 6 inches (2.896 meters). The Piper L-4H Grasshopper had an approximate empty weight of 740 pounds (336 kilograms), depending on installed equipment, and a maximum gross weight of 1,220 pounds (553 kilograms).

Piper L-4 Grasshopper (T. O. NO. 01-140DA-3, Structural Repair Instructions, at Page 2)

The Grasshopper was powered by an air-cooled, normally-aspirated, 171.002-cubic-inch-displacement (2.802 liter) Continental O-170-3 (Continental A65-8), horizontally-opposed four-cylinder overhead-valve engine with a compression ratio of 6.3:1. It was rated at 65 horsepower at 2,300 r.p.m. at Sea Level for takeoff, and required a minimum of 73-octane gasoline. The direct-drive engine turned a two-blade fixed-pith propeller with a diameter of 6 feet, 0 inches (1.829 meters).

The L-4H had a maximum speed of 90 miles per hour (145 kilometers per hour), and an absolute ceiling of 14,000 feet (4,267 meters). With a fuel capacity of 12 U.S. gallons (45.4 liters), its maximum range was 206 miles (332 kilometers).
