22 April 1912: Departing at 5:47 a.m., Denys Corbett-Wilson flew his Blériot XI from Fishguard and Goodwick, Pembrokeshire, Wales, across St. George’s Channel and landed at Crane, near Enniscorthy, County Wexford, Ireland, 1 hour, 40 minutes later. This was the first crossing of the Irish Sea from England to Ireland by air.

Lieutenant Denys Corbett-Wilson

Corbett-Wilson, having flown in heavy rain for the final half hour, with an erratic compass and misfiring engine, saw a field at Crane that he thought was suitable for landing his airplane. The area was too small, though, and he ran into heavy brush, slightly damaging the Blériot.

The damaged airplane was stored at the stables of Lord Donoughmore’s Estate. Many years later the estate was sold and the wreck was purchased. It was later donated to a museum in Kilkenny.

Denys Corbett-Wilson was born at Thames Ditton, Surrey, England, on Christmas Eve, 24 December 1882. He was the son of W.H.C. Wilson, Esq., Barrister-at-Law, and Ada Caroline Corbett-Wilson.

Corbett-Wilson learned to fly at Pau, France in 1911. A sportsman and “an intrepid rider to hounds,” he joined the Royal Flying Corps at the beginning of World War I and was commissioned a second lieutenant, Special Reserve, Royal Flying Corps. He served with No. 3 Squadron at Béthune, France, and was promoted to lieutenant in November 1914.

Lieutenant Denys Corbett-Wilson was killed in action while on a reconnaissance flight along the Western Front, 10 May 1915. His airplane, a Morane-Saulnier Type L, was struck by an artillery shell. He was buried with full military honors at Fournes-en-Weppes by the German Army.

The Blériot XI was a single-seat, single-engine monoplane, designed by Raymond Saulnier and built by Louis Charles Joseph Blériot. It was 24 feet, 11 inches (7.595 meters) long with a wingspan of 27 feet, 11 inches (8.509 meters) and overall height of 8 feet, 10 inches (2.692 meters). The wings had a chord of 6 feet (1.829 meters). The airplane had an empty weight of 507 pounds (229.9 kilograms).

In its original configuration, the airplane was powered by an air-cooled, 3.774 liter (230.273 cubic inches) R.E.P.  two-row, seven-cylinder fan engine (or “semi-radial”) which produced 30 horsepower at 1,500 r.p.m., driving a four-bladed paddle-type propeller. The R.E.P. engine weighed 54 kilograms (119 pounds). This engine was unreliable and was soon replaced by an air-cooled 3.534 liter (215.676 cubic inch) Alessandro Anzani & Co., 60° (some sources state 55°) three-cylinder “fan”-type radial engine (or W-3) and a highly-efficient Hélice Intégrale Chauvière two-bladed fixed-pitch propeller, which had a diameter of 6 feet, 8 inches (2.032 meters).

The Anzani W-3 was a direct-drive, right-hand tractor engine which produced 25 horsepower at 1,400 r.p.m. It was 1.130 meters (3 feet, 8.49 inches) long, 1.500 meters (4 feet, 11.01 inches) high, and 0.720 meters (2 feet, 4.35 inches) wide. The engine weighed 66 kilograms (145.5 pounds).

After 1910, the Blériot XI was often equipped with a Gnome rotary engine. This was a normally-aspirated, air-cooled, 7.983 liter (487.140-cubic-inch-displacement) Société des Moteurs Gnome Omega 7-cylinder rotary engine which produced 50 horsepower at 1,200 r.p.m. The direct-drive engine turned a two-bladed wooden propeller in a left-hand, tractor configuration. The Omega 7 is 79.2 centimeters (2 feet, 7.2 inches) long, 83.8 centimeters (2 feet, 9.0 inches) in diameter, and weighs 75.6 kilograms (166.7 pounds). The prototype of this engine is in the collection of the Smithsonian Institution National Air & Space Museum.

The Blériot XI had a maximum speed of 47 miles per hour (76 kilometers per hour) and the service ceiling was (3,280 feet) 1,000 meters.

21 April 1972, 02:23:35 UTC: Lunar Module Orion (LM-11) touched down on the surface of the Moon at the Descartes Highlands. On board were the Mission Commander, Captain John Watts Young, United States Navy, and Lunar Module Pilot Lieutenant Colonel Charles M. Duke, Jr., United States Air Force. They were the ninth and tenth humans to stand on the Moon.

Technical problems delayed Orion‘s descent for three orbits. Lieutenant Commander Thomas K. (Ken) Mattingly II, U.S.N., the Command Module Pilot, remained in lunar orbit aboard Casper (CSM-113).

As they neared the surface they started to see dust blowing at about 80 feet (24 meters). The lunar module hovered briefly before continued downward.

104:29:22 Duke: Okay, 2 down. Stand by for contact. Come on, let her down. You leveled off. (Pause) Let her on down. Okay, 7. . . 6 percent [fuel remaining]. Plenty fat.

104:29:36 Duke: Contact! Stop. (Pause while they drop to the surface) Boom.

During a debriefing, John Young said,

“When we got the Contact light, I counted ‘one-potato’ and shut the engine down. The thing fell out of the sky the last three feet. I know it did. I don’t know how much we were coming down, maybe a foot a second.”  ¹

20–21 April 1964: Nearly ten years after the first flight of the Lockheed YC-130 Hercules prototype, the Lockheed Model 382, serial number 3946, the commercial version of the military C-130E, made the longest first flight in history when it flew for 25 hours, 1 minute, after taking off from Marietta, Georgia.

The flight crew, led by Chief Production Pilot Joe Garrett, flew the Hercules in a racetrack pattern over Georgia and Alabama, and for all but 36 minutes of the flight, the outboard engines were shut down and their propellers feathered.

The Lockheed Model 382 was certified by the Federal Aviation Administration 16 February 1965.

N1130E was retained by Lockheed as a demonstrator, however it was briefly leased to Alaska Airlines in March 1965, and returned the following month.

The L-382 was converted to the L382E-44K-20 standard in April 1968, with a 5 foot, 0 inch (1.524 meters) segment added to the fuselage behind the cockpit, and a 3 foot, 4 inch (1.016 meter) section behind the wing.

N1130E was leased to Delta Air Lines in October 1968, and returned after six months.

Lockheed sold N1130E to Pepsico Airlease Corporation, who leased the freighter to Flying W Airways. It was reregistered as N50FW. In March 1973 Pepsico sold it to Philippine Aerotransport and it was operated for the Philippine government, first as PI-97, then RP-97, and finally, RP-C97. The Hercules was placed in storage in March 1981. With a total flight time of 13,144.8 hours, it was scrapped 18 February 2014.

LIEUTENANT EDWARD HENRY O’HARE
UNITED STATES NAVY

Medal of Honor – Navy

“The President takes pleasure in presenting the Congressional Medal of Honor to Lieutenant Edward H. O’Hare, U.S. Navy, for services as set forth in the following Citation:

” ‘For conspicuous gallantry and intrepidity in aerial combat, at grave risk of his life above and beyond the call of duty, as section leader and pilot of Fighting Squadron 3, when on February 20, 1942, having lost the assistance of his teammates, he interposed his plane between his ship and an advancing enemy formation of nine attacking twin-engined heavy bombers. Without hesitation, alone and unaided he repeatedly attacked this enemy formation at close range in the face of their intense combined machine-gun and cannon fire, and despite this concentrated opposition, he, by his gallant and courageous action, his extremely skillful marksmanship, making the most of every shot of his limited amount of ammunition, shot down five enemy bombers and severely damaged a sixth before they reached the bomb release point.

” ‘As a result of his gallant action, one of the most daring, if not the most daring single action in the history of combat aviation, he undoubtedly saved his carrier from serious damage.’ “

—Franklin Delano Roosevelt, Thirty-third President of the United States, his remarks on the presentation of the Medal of Honor, 21 April 1942, at the White House, Washington, D.C. The American Presidency Project.

15–21 April 1928: Carl Benjamin (“Ben”) Eielson and George Hubert Wilkins, M.C. and Bar, flew from Point Barrow on the northern coast of Alaska across the Arctic Ocean to Spitsbergen, Svalbard, Norway. The distance was approximately 2,200 miles (3,540 kilometers). The crossing took about 20 hours, and was the first Arctic crossing by air. Their airplane was a Lockheed Vega, civil registration NX3903, the third aircraft of the type to be built.

Eielson and Wilkins had made a prior attempt about a week earlier, but attempting to takeoff with a crosswind, had damaged the skis on the Vega. A spare set made of wood had been brought along and these were installed and after some delay, finally took off on April 15th.

The planned route of flight was over the Canadian Arctic Islands and then around north Greenland then on to Spitsbergen, a large island in the Svalbard Archipelago, under the jurisdiction of Norway. Because of the proximity to the Magnetic Pole, a compass would have been useless for navigation. Hubert Wilkins used a Mk. V bubble sextant to calculate their position by taking sights of the sun which remained above the horizon for the entire duration of the flight.

They encountered head winds, cloudy weather and storms. The air temperature was -45 °C. (-49 °F.). As they estimated that they were nearing their destination, they encountered a severe snow storm. With fuel running low, the descended to look for a possible landing site. They were able to land on Deadman’s Island, off the north coast of Danskøya (Dane’s Island). The severe weather closed in and the fliers were stranded for 4 days. When it finally cleared enough for them to continue their journey there was some difficulty as the wooden skis kept freezing to the surface. After they took off and climbed to 3,000 feet (914.4 meters) they immediately sighted the radio towers of  Grønfjorden on Nordenskiöld Land, their actual destination.

Sir George Hubert Wilkins, M.C. and Bar.

Of their flight, famed Norwegian explorer Roald Amundsen said, “No flight has been made anywhere, at any time, which could be compared with this.”

The Lockheed Vega was a very state-of-the-art aircraft for its time. The prototype flew for the first time 4 July 1927 at Mines Field, Los Angeles, California. It used a streamlined monocoque fuselage made of molded plywood. The wing and tail surfaces were fully cantilevered, requiring no bracing wires or struts to support them.

The Vega was flown by one pilot in an open cockpit and could carry four passengers in the cabin. It was 27 feet, 6 inches (8.382 meters) long with a wingspan of 41 feet, 0 inches (12.497 meters) and overall height of 8 feet, 2 inches (2.489 meters). The airplane had an empty weight of 1,875 pounds (851 kilograms) and a gross weight of 3,470 pounds (1,574 kilograms).

The early Vegas were powered by an air-cooled, normally-aspirated 787.26-cubic-inch-displacement (12.901 liter) Wright Whirlwind J-5C nine-cylinder radial engine with a compression ratio of 5.1:1. It was rated at 200 horsepower at 1,800 r.p.m., and 225 horsepower at 2,000 r.p.m. This was a direct-drive engine which turned a two-bladed Hamilton Standard propeller. The Wright J-5C was 2 feet, 10 inches (0.864 meters) long and 3 feet, 9 inches (1.143 meters) in diameter. It weighed 508 pounds (230.4 kilograms).

The Vega had a cruising speed of 118 miles per hour (190 kilometers per hour) and atop speed of 138 miles per hour (222 kilometers per hour)—very fast for its time. The airplane’s range was 900 miles (1,448.4 kilometers). It could fly at an altitude 15,000 feet (4,572 meters).
