18 November 1978: At Lambert Field, St, Louis, Missouri, McDonnell Douglas Corporation Chief Test Pilot John Edward (“Jack”) Krings, took the number one Full Scale Development (FSD) F/A-18A-1-MC Hornet, Bu. No. 160775, for its first flight. During the 50-minute test flight, Krings flew the Hornet to 24,000 feet (7,315 meters) before returning to STL.

The F/A-18 Hornet was developed for the United States Navy from the prototype Northrop YF-17, a competitor for a U.S. Air Force fighter program. (The rival General Dynamics F-16 was selected for production.) Initially, it was planned that there would be fighter variant, the F-18, and a ground attack version, the A-18. The Navy and manufacturers determined that s single airplane could perform both assignments. The Hornet is produced by McDonnell Douglas, with Northrop Corporation as the prime subcontractor.

The F/A-18 remains in production as the Boeing F/A-18E Super Hornet.

McDonnell Douglas F/A-18A-1-MC Hornet Bu. No. 160775 is on static display at Naval Air Warfare Center Weapons Division (NAWCWD) China Lake, near Ridgecrest, California.

14 November 1974: The very first operational McDonnell Douglas F-15A Eagle air superiority fighters were delivered to the 555th Tactical Training Squadron, 58th Tactical Training Fighter Wing at Luke Air Force Base, west of Phoenix, Arizona. The acceptance ceremony was presided over by President Gerald R. Ford.

“. . . I am here today to underscore to you and to the world that this great aircraft was constructed by the American people in the pursuit of peace. Our only aim with all of this aircraft’s new maneuverability, speed, and power is the defense of freedom.

“I would rather walk a thousand miles for peace than to have to take a single step for war.

“I am here to congratulate you: the United States Air Force, McDonnell Douglas, Pratt and Whitney, all of the many contractors and workers who participated in this very, very successful effort, as well as the pilots who have so diligently flight-tested the F-15 Eagle. All of you can underline my feeling that we are still pilgrims on this Earth, and there still is a place for pioneers in America today.”

The F-15A Eagle is a Mach 2.5+ fighter with outstanding acceleration and maneuverability. The F-15A was produced from 1972 to 1979. It is a single-seat, twin-engine air superiority fighter, 63 feet, 9 inches (19.431 meters) long, with a wingspan of 42 feet, 9½ inches (13.043 meters) and overall height of 18 feet, 5½ inches (5.626 meters). The F-15A has an empty weight of 27,000 pounds (12,247 kilograms) and its maximum takeoff weight (MTOW) is 66,000 pounds (29,937 kilograms).

The F-15A is powered by two Pratt & Whitney JTF22A-25A (F100-PW-100) afterburning turbofan engines capable of producing 14,670 pounds of thrust (65.255 kilonewtons), and 23,830 pounds (105.996 kilonewtons), each, with afterburner. The F100 is a two-spool, axial-flow turbine engine with a 3-stage fan section; 10-stage compressor; single chamber combustion section; and 4-stage turbine (2 low- and 2 high-pressure stages). The F100-PW-100 is 191 inches (4.851 meters) long, 46.5 inches (1.181 meters) in diameter, and weighs 3,035 pounds (1,376.7 kilograms).

The cruise speed of the F-15A Eagle is 570 miles per hour (917 kilometers per hour). It has a maximum speed of 915 miles per hour (1,473 kilometers per hour) at Sea Level, and 1,650 miles per hour (2,655 kilometers per hour) at 36,000 feet (10,973 meters). The service ceiling is 65,000 feet (19,812 meters). It can climb in excess of 50,000 feet per minute (254 meters per second), and with a thrust-to-weight ratio of 1.15:1, could climb straight up. The Eagle’s combat radius is 1,222 miles (1,967 kilometers).

The F-15A is armed with one General Electric M61A1 Vulcan 20mm rotary cannon with 940 rounds of ammunition, four AIM-7 Sparrow radar-guided missiles and four AIM-9 Sidewinder heat-seeking missiles.

384 F-15A Eagles were built before production shifted to the improved F-15C version. As F-15Cs became operation, the F-15As were transferred to Air National Guard units assigned to defend continental U.S. airspace. The last F-15A was retired from service in 2009.

29 August 1970: The McDonnell Douglas prototype widebody airliner, DC-10-10, N10DC, made its first flight from Long Beach Airport to Edwards Air Force Base, California, where it underwent flight testing and F.A.A. certification. The aircraft commander was the company Project Pilot, Clifford L. Stout, with Deputy Chief Engineering Pilot Harris C. Van Valkenburg as co-pilot. John D. Chamberlain was the flight engineer and the flight test engineer was Shojun Yukawa.

During the first flight the DC-10 reached 300 knots (345.2 miles per hour, 555.6 kilometers per hour) and 30,000 feet (9,144 meters). The primary purpose of this flight was to check the airliner’s basic flight characteristics, aircraft systems and the installed test equipment. The flight lasted 3 hours, 36 minutes.

During the test program, N10DC made 989 test flights, accumulating 1,551 flight hours. It was put into commercial service with American Airlines 12 August 1972, re-registered as N101AA.

The DC-10 was a wide-body commercial airliner designed for medium to long range flights. It was flown by a crew of three and depending on the cabin arrangement, carried between 202 and 390 passengers. The DC-10-10 was 170 feet, 6 inches (51.968 meters) long with a wingspan of 155 feet, 4 inches (47.346 meters) and overall height of 58 feet, 1 inch (17.704 meters). The airliner had an empty weight of 240,171 pounds (108,940 kilograms) and maximum takeoff weight of 430,000 pounds (195,045 kilograms). It was powered by three General Electric CF6-6D turbofan engines, producing 40,000 pounds of thrust (177.93 kilonewtons), each. These gave the DC-10 a maximum cruise speed of Mach 0.88 (610 miles per hour, 982 kilometers per hour). Its range is 3,800 miles (6,116 kilometers) and the service ceiling is 42,000 feet (12,802 meters).

In production from 1970 to 1988, a total of 386 DC-10s were built in passenger and freighter versions. 122 were the DC-10-10 variant. Another 60 KC-10A Extender air refueling tankers were built for the U.S. Air Force and 2 KDC-10 tankers for the Royal Netherlands Air Force.

The first McDonnell Douglas DC-10 was in service with American Airlines from 12 August 1972 to 15 November 1994 when it was placed in storage at Tulsa, Oklahoma. The 24-year-old airliner had accumulated 63,325 flight hours.

After three years in storage, the first DC-10 returned to service flying for Federal Express. In 1998 it was modernized as an MD-10 and re-registered again, this time as N530FE. It was finally retired from service and scrapped at Goodyear, Arizona in 2002.
