6 September 1919: Major Rudolph William Schroeder, Chief Test Pilot of the Engineering Division, McCook field, Ohio, with Lieutenant George W. Elsey as a passenger, flew a Packard Lepère L USA C.II biplane to two Fédération Aéronautique Internationale (FAI) World Records, reaching an altitude of 8,616 meters (28,268 feet).¹ ²

The biplane was powered by a turbo-supercharged 1,649.3-cubic-inch-displacement (27.028 liter) liquid-cooled Liberty L-12 single overhead cam (SOHC) 45° V-12 engine which produced 449 horsepower at 2,000 r.p.m. Aeronautical engineer Dr. Sanford Alexander Moss developed the use of a turbocharger on aircraft engines.

The Packard Lepère L USA C.II was a World War I biplane designed by French aeronautical engineer Captain Georges Lepère and built by the Packard Motor Car Company of Detroit, Michigan. It was to have been a two-place fighter, light bomber and observation aircraft armed with four machine guns.

The Packard Lepère was 25 feet, 3-1/8 inches (7.699 meters) long. The upper and lower wings had an equal span of 41 feet, 7¼ inches (12.681 meters), and equal chord of 5 feet, 5¾ inches (1.670 meters). The vertical gap between the wings was 5 feet, 5/8-inch (1.527 meters) and the lower wing was staggered 2 feet, 15/16-inch (0.633 meters) behind the upper wing. The wings’ incidence was +1°. Upper and lower wings were equipped with ailerons, and had no sweep or dihedral. The height of the Packard Lepère, sitting on its landing gear, was 9 feet, 7 inches (2.921 meters). The Packard Lepère had an empty weight of 2,561.5 pounds (1,161.9 kilograms) and its gross weight was 3,746.0 pounds (1,699.2 kilograms).

The fuselage was a wooden structure with a rectangular cross section. It was covered with three layers of veneer, (2 mahogany, 1 white wood) with a total thickness of 3/32-inch (2.38 millimeters). The fuselage had a maximum width of 2 feet, 10 inches (0.864 meters) and maximum depth of 4 feet, 0 inches (1.219 meters).

The wings were also of wooden construction, with two spruce spars and spruce ribs. Three layers of wood veneer covered the upper surfaces. Heavy bracing wires were used. These had an airfoil cross-section and actually provided additional lift. The interplane struts were unusual in that they were fully-framed units.

The Packard Lepère was powered by a water-cooled, normally-aspirated, 1,649.336-cubic-inch-displacement (27.028 liter) Liberty L-12 single overhead cam (SOHC) 45° V-12 engine with a compression ratio of 5.4:1. The Liberty produced 408 horsepower at 1,800 r.p.m. The L-12 as a right-hand tractor, direct-drive engine and it turned turned a two-bladed, fixed-pitch wooden propeller. The Liberty 12 was 5 feet, 7.375 inches (1.711 meters) long, 2 feet, 3.0 inches (0.686 meters) wide, and 3 feet, 5.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).

The engine coolant radiator was positioned horizontally in the center section of the Lepère’s upper wing. Water flowed through the radiator at a rate of 80 gallons (303 liters) per minute.

The Packard Lepère had a maximum speed of 130.4 miles per hour (209.9 kilometers per hour) at 5,000 feet (1,524 meters), 127.6 miles per hour (205.4 kilometers per hour) at 10,000 feet (3,048 meters), 122.4 miles per hour (197.0 kilometers per hour) at 15,000 feet (4,572 meters), 110.0 miles per hour (177.0 kilometers per hours) at 18,000 feet (5,486 meters) and 94.0 miles per hour (151.3 kilometers per hour) at 20,000 feet (6,096 meters). Its cruising speed was 112 miles per hour (180 was kilometers per hour). The airplane could climb to 5,000 feet in 4 minutes, 24 seconds, and to 20,000 feet in 36 minutes, 36 seconds. In standard configuration, the Packard Lepère had a service ceiling of 20,200 feet (6,157 meters). Its range was 320 miles (515 kilometers).

The fighter’s armament consisted of two fixed M1918 Marlin .30-caliber aircraft machine guns mounted on the right side of the fuselage, synchronized to fire forward through the propeller arc, with 1,000 rounds of ammunition, and two M1918 Lewis .30-caliber machine guns on a flexible mount with 970 rounds of ammunition.

The Air Service had ordered 3,525 of these airplanes, but when the War ended only 28 had been built. The contract was cancelled.

Six Packard Lepères were used for flight testing at McCook Field, Dayton, Ohio, assigned project numbers P 44, P 53, P 54, P 65, P 70 and P 80. One of these, flown by Major Rudolph W. Schroeder, set two Fédération Aéronautique Internationale (FAI) World Records for Altitude at 9,455 meters (31,020 feet), 18 September 1918.¹ On 6 September 1919, Schroeder flew a Packard Lepère to 8,616 meters (28,268 feet) while carrying a passenger. This set two more World Altitude Records.² Flying P 53, A.S. 40015, he set a fifth FAI altitude record of 10,093 meters (33,114 feet), 27 February 1920.³ On 28 September 1921, Captain John A. Macready flew P 53 to an altitude of 40,800 feet (12,436 meters). On 13 October 1922, 1st Lieutenant Theodore J. Koenig flew P 53 to win the Liberty Engine Builders’ Trophy Race at Selfridge Field, near Mount Clemens, Michigan. Koenig completed ten laps of the triangular racecourse in 2:00:01.54, at an average speed of 128.8 miles per hour (207.3 kilometers per hour).

The only Packard Lepère in existence, serial number A.S. 42133, is in the collection of the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

5 September 1984: Space Shuttle Discovery, OV-103, completed its first space flight, STS-41-D,  when it landed at Edwards Air Force Base, California, at 6:37 a.m. PDT (13:37:54 UTC), 5 September 1984. It had completed 97 orbits of the Earth. The total duration of its flight was 6 days, 56 minutes, 4 seconds.

The purpose of the mission was to place three communications satellites into orbit, and to deploy an experimental solar panel array. Various other experiments were also carried out.

The Mission Commander was Henry W. Hartsfield, Jr., making his second space flight. Shuttle Pilot Michael L. Coats was on his first. Three Mission Specialists, Richard M. Mullane, Steven A. Hawley, Judith A. Resnick, and Payload Specialist Charles D. Walker, were all on their first space flight.

A highlight of this mission was the onboard filming by the crew of footage for the IMAX film, The Dream Is Alive.

Discovery is the space shuttle fleet leader, having made 39 orbital flights, more than any other shuttle.

Mission Specialist Judith Arlene Resnick was a crew member of shuttle mission STS-51-L. She was killed when Challenger was destroyed shortly after launch, 28 January 1986.

5 September 1983: A Strategic Air Command Boeing KC-135A Stratotanker of the 42nd Air Refueling Squadron, Loring  AFB, Maine, was sent to rendezvous with a flight of McDonnell Douglas F-4E Phantom II fighter bombers crossing the Atlantic Ocean enroute to Europe. As they began to refuel the fighters, one F-4E began to lose power in one of its engines, and also lost part of its hydraulic system. The Phantom’s pilot had difficulty maintaining speed and altitude as he tried to hook up with the tanker, and the second engine began to overheat. The two aircraft flew at just above the Stratotanker’s landing speed so that the Phantom could keep up, but as it slowed further, the Phantom’s angle of attack had to increase to maintain lift. This exceeded the mechanical limits of the refueling boom and the two airplanes separated without the fighter having received a full fuel load.

The crew of the F-4E was in serious danger. It was unlikely that the airplane could remain in the air for much longer. It was decided to head for Gander, Newfoundland, the closest place to land, 500 miles (806 kilometers) away. Captain Robert J. Goodman, U.S. Air Force, aircraft commander of the Stratotanker, decided to escort the crippled fighter which continued to lose altitude. It was necessary to try to refuel it three more times, and on occasion, the tanker actually towed the fighter back to altitude.

With the help of the tanker, the Phantom II finally arrived at Gander and landed safely.

For their efforts to save the lives of the crew of the F-4E, Captain Goodman and his crew, Captain Michael F. Clover, 1st Lieutenant Karol F. Wojcikowski and Staff Sergeant Douglas D. Simmons, Crew E113, were awarded the Mackay Trophy “For outstanding achievement while on a routine refueling mission involving F-4E aircraft, saving a valuable aircraft from destruction and its crew from possible death.”

The Mackay Trophy which is awarded annually for “the most meritorious flight of the year by an Air Force person, persons, or organization.” It is kept at the Smithsonian Institution, National Air and Space Museum.
