Boeing 314 NC18603, Yankee Clipper (Harris & Ewing)
24 June 1939: The Pan American Airways System began scheduled air service from the United States to Britain. The Boeing 314 Yankee Clipper, NC18603, made the first flight from Port Washington, New York, departing at 8:21 a.m. It made intermediate stops at Shediac, New Brunswick, and Botwood, Newfoundland, where fog delayed the flying boat until 12:49 p.m., 28 June. Continuing across the Atlantic, Yankee Clipper made another stop at Foynes, Ireland, and finally arrived at Southampton at 7:25 p.m. that evening.
The largest airplane of the time, the Pan American Clipper flying boat could carry 77 passengers in “one class” luxury, with a ticket priced at $675—that’s in 1939 dollars. ($12,389.82 in 2020) Uniformed waiters served five and six course meals on silver service. Seats could be folded down into beds.

The Boeing Model 314 was a large four-engine, high-wing monoplane flying boat designed and built by the Boeing Airplane Company to take off and land on water. It had a crew of 10. The wings and engine nacelles had been designed for Boeing XB-15 heavy bomber. It was 106 feet (32.309 meters) long with a wingspan of 152 feet (46.330 meters). It had a maximum take off weight of 82,500 pounds (37,421 kilograms).
The Boeing 314 was powered by four air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.668 liter) Wright Aeronautical Division Cyclone 14 GR2600A2, two-row, 14-cylinder radial engines with a compression ratio of 7.1:1. They were rated at 1,200 horsepower at 2,100 r.p.m., and 1,550 horsepower at 2,400 r.p.m. for takeoff, burning 91/96 octane gasoline. These engines (also commonly called “Twin Cyclone”) drove three-bladed Hamilton Standard Hydromatic full-feathering constant-speed propellers with a diameter of 14 feet (4.267 meters) through a 16:9 gear reduction. The GR2600A2 was 5 feet, 2.06 inches (1.576 meters) long and 4 feet, 7 inches (1.387 meters) in diameter. It weighed 1,935 pounds (878 kilograms). The engines could be serviced in flight, with access through the wings.

The Boeing 314 had a maximum speed of 199 miles per hour (320 kilometers per hour), with a range of 3,685 miles (5,930 kilometers) at its normal cruising speed of 183 miles per hour (295 kilometers per hour). Its service ceiling was 13,400 feet (4,084 meters). The fuel capacity was 4,246 gallons (16,073 liters).
Boeing built six Model 314 and another six 314A flying boats for Pan American Airways and British Overseas Airways Corporation.
Yankee Clipper was destroyed 22 February 1943 at Lisbon, Portugal. A wing hit the water on landing. 24 of the 39 persons aboard were killed.

24 June 1937: Leg 24a, 24b. After three days of maintenance and repair work on her Lockheed Electra at Bandoeng, Java, Dutch East Indies, Amelia Earhart started warming up her engines at 3:45 a.m. in preparation for a long transoceanic flight to Darwin, Australia.
However, problems with an instrument delayed the takeoff until 2:00 p.m., making Darwin much too far away. They didn’t want to arrive there during hours of darkness. If Fred Noonan’s navigation was slightly off after a long over water flight during darkness, they might not find the small airport.
Instead, they made a short hop to Batavia (now known as Jakarta) and from there, continued on to Soerabaya for a total distance for the day of 355 miles (571.3 kilometers).
“After that late start we reached Soerabaya when the descending sun marked declining day. In the air, and afterward, we found that our mechanical troubles had not been cured. Certain further adjustments of faulty long-distance flying instruments were necessary, and so I had to do one of the most difficult things I had ever done in aviation. Instead of keeping on I turned back the next day to Bandoeng.“

22–24 June 1937: Amelia Earhart’s Lockheed Electra 10E Special, NR16020, undergoes maintenance at Bandoeng, Java, Dutch East Indies, while Amelia and Fred Noonan visit a volcano.
“I went for an inspection trip myself. My first objective was an active volcano, to the crater rim of which one can drive in half an hour up a beautiful mountain road. . . At 5,000 feet the trees began to dwarf and the vegetation became less dense. At 6,500, only scrub trees which bred in and soil persisted. I could smell sulfur fumes for some time before rounding the last curve leading to the lower edge of the pit. Hundreds of feet below, emerald water had collected in a pool at the bottom. Here and there jets of yellow-white steam issued from crevices. . . .”

23 June 1961: Major Robert Michael White, United States Air Force, became the first pilot to exceed Mach 5 in an aircraft. This was the 38th flight of the X-15 Program. Flights during this phase incrementally increased the speed and altitude of the X-15 up to its design limits of Mach 6 and 250,000 feet (76,200 meters).
The second North American Aviation X-15A, 56-6671, was air-dropped from the NB-52A Stratofortress mothership, 52-003, over Mud Lake, Nevada at 2:00:05.0 p.m., Pacific Daylight Time (21:00 UTC). White fired the Reaction Motors XLR99-RM-1 engine for 78.7 seconds, reaching Mach 5.27 (3,603 miles per hour, 5,799 kilometers per hour) and climbed to 107,700 feet (32,827 meters). 10 minutes, 5.7 seconds after being dropped from the B-52, White touched down on Rogers Dry Lake at Edwards Air Force Base.
Bob White was the first pilot to exceed Mach 4, Mach 5 and Mach 6. He also flew an X-15 to an altitude of 314,750 feet (95,936 meters), qualifying for U.S. Air Force astronaut wings.
After leaving the X-15 program, Major White flew 70 combat missions in the Republic F-105D Thunderchief fighter bomber during the Vietnam War. He lead the attack against the heavily-defended Paul Doumer Bridge in Hanoi, 11 August 1967, for which he was awarded the Air Force Cross.
Major General White retired from the U.S. Air Force in 1981. He died 10 March 2010.
56-6671 is in the collection of the National Museum of the United States Air Force. The mothership, 52-003, is on display at the Pima Air and Space Museum, Tucson, Arizona.
Grumman F9F-5 Panther Bu. No. 125228 explodes after striking the flight deck of USS Midway (CVB-41), 23 June 1951. (U.S. Navy)
23 June 1951: Operating in the Atlantic Ocean off the Virginia Capes, the United States Navy aircraft carrier USS Midway (CVB-41) was conducting suitability trials of the Grumman F9F-5 Panther. Commander George Chamberlain Duncan, commanding Fighter Squadron 51 (VF-51), was in the cockpit of Bu. No. 125228. Having made a successful landing aboard Midway, Duncan took off to make another approach and landing.
Just short of the flight deck, the Panther dropped below the correct approach. Duncan tried to pull up, but the fighter struck the ramp and broke in half. The aircraft exploded in flames. The forward section slid down the deck. Duncan, though burned, was quickly rescued.

The Grumman F9F-5 Panther was a single-seat, single-engine turbojet powered fighter designed for operation from the U.S. Navy’s aircraft carriers. It was 38 feet, 10½ inches (11.849 meters) long, with a wingspan of 38 feet, 0 inches (11.528 meters)— not including wing tanks. Its overall height was 12 feet, 4 inches (3.759 meters). The wings could be hydraulically folded to reduce the span for storage aboard ship. The F9F-5 weighed 10,147 pounds (4,603 kilograms) empty, and had a gross weight of 17,766 pounds (8,059 kilograms). The maximum takeoff weight (MTOW) was 18,721 pounds (8,492 kilograms).
The F9F-5 was powered by a Pratt & Whitney JT7 (J48-P-6 or -6A) engine, a license-built version of the Rolls-Royce Tay. It was a single-shaft turbojet with a single-stage centrifugal-flow compressor, 9 combustion chambers and a single-stage axial-flow turbine. The J48-P-6 was rated at 6,250 pounds of thrust (27.80 kilonewtons), and 7,000 pounds (31.14 kilonewtons) with water injection.
The F9F-5 Panther had a cruise speed 481 miles per hour (774 kilometers per hour). Its maximum speed was 604 miles per hour (972 kilometers per hour) at Sea Level. Its service ceiling was 42,800 feet (13,045 meters), and the range was 1,300 miles (2,092 kilometers).
The Panther was armed with four M3 20 mm autocannon placed in the nose. It could carry up to 3,465 pounds (1,361 kilograms) of bombs or eight 5-inch (12.7 centimeters) rockets on four hardpoints under each wing.
The XF9F-2 prototype first flew 21 November 1947. 1,382 F9F Panthers were produced and they remained in service with the U.S. Navy and Marine Corps until 1958. 619 of these were the F9F-5 variant. A swept wing version, the F9F-6 through F9F-9J Cougar, was also produced.
Captain George Chamberlain Duncan, United States Navy
George Chamberlain Duncan was born at Tacoma, Washington, 11 Feb 1917. He was the first of three children of of George W. Duncan, a mining camp supplier, and Frances Delarsh Chamberlain Duncan. Duncan attended Stadium High School in Tacoma. He played on the football and swim teams. He was also a member of the glee club, and during his senior year, portrayed “Oliver le Dain” in the comic opera, “The Vagabond King.” He was a member of the school’s glider and architecture clubs.

George Duncan entered the United States Naval Academy, Annapolis, Maryland, as a midshipman, 18 July 1935. He graduated 1 June 1939 and was commissioned an Ensign, United States Navy. Ensign Duncan served aboard the Colorado-class battleship USS West Virginia (BB-48) from June 1939 to August 1941.
Ensign Duncan married Miss Agnes Wirt Tawresey at Washington, D.C., 30 August 1941. They would have four children, three sons, George, Jr., Richmond, Alfred, and a daughter, Agnes.
Ensign Duncan was next assigned to the Northampton-class heavy cruiser USS Louisville (CA-28), serving aboard in 1942 and 1943.
Duncan was promoted to the rank of lieutenant (junior grade), 1 June 1942. Two weeks later, 15 June 1942, he was promoted to lieutenant (temporary).
Lieutenant Duncan underwent flight training at NAS Pensacola. Following graduation he was assigned to Fighting Squadron Fifteen (VF-15) aboard USS Essex (CV-9). Duncan was promoted to lieutenant commander (temporary) 15 March 1944.
On 13 September 1944, Lieutenant Commander Duncan was engaged in aerial combat over the central Philippine Islands. He was credited with destroying an enemy medium bomber and two fighters, shared credit for a second bomber shot down, and damaged a third fighter. He followed this by strafing an airfield and destroying three aircraft on the ground. For these actions, Duncan was awarded the Silver Star.
During the Battle off Cape Engaño on the morning of 25 October 1944, Lieutenant Commander Duncan led VF-15 in an attack against Imperial Japanese Navy warships in the Sibuyan Sea. He scored a direct hit with a bomb on the light carrier IJN Chitose, which, along with a number of other hits, resulted in its sinking at 0937 hours. Duncan was awarded the Navy Cross.
