The pilot started a night approach to Mobile Airport when he encountered severe turbulences. He lost control of the airplane that crashed few hundred yards short of runway threshold. A passenger was injured while three other occupants were killed. At the time of the accident, the airport was closed (closing times are 0000LT till 0600LT) and there was no ATC employee at tower.

While on a night mail flight from Cincinnati to Nashville, the pilot encountered poor weather conditions upon arrival. On approach, he lost control of the airplane that dove into the ground and crashed in Brentwood, about 7 miles southwest of Nashville Airport. The aircraft was destroyed and the pilot, sole on board, was killed.

Upon landing at Chevak, the right main gear collapsed. The airplane veered off runway and came to a halt. All nine occupants escaped uninjured but the aircraft was considered as damaged beyond repair.

While cruising under VFR mode, the pilot informed ATC about the sudden deterioration of the weather conditions and request assistance which was not available at that time. Shortly later, while flying in heavy rain falls and thunderstorm activity, the airplane struck a hillside and crashed. All three occupants were killed.

The flight departed New York-JFK to carry out training and proficiency check manoeuvres at the National Aviation Facilities Experimental Center (NAFEC) at the Atlantic City Airport. The first captain to receive the proficiency check occupied the left seat. The instructor-pilot occupied the right seat, and a flight engineer occupied the flight engineer's position. The other two captains occupied the flight deck as observers while awaiting their turn at the controls. Flight 5787 landed on runway 13 then requested, and the tower approved, clearance to taxi to the end of the runway, execute a 180 degrees turn, and take off on runway 31. Prior to takeoff, the instructor pilot briefed the captain to expect a simulated engine failure after V1, to execute a three-engine climbout, and to request vectors for a precision ILS approach to runway 13, using the aircraft's flight director system. Take off was initiated at 12:20 and instructor pilot retarded the No. 4 engine to training idle thrust after V1 had been reached. The takeoff was continued and emergency procedures were executed in accordance with the TWA engine failure emergency checklist. The aircraft was leveled off at 1,500 feet and vectored to intercept the ILS course in the vicinity of the outer marker. The No. 4 engine remained in idle thrust and the instructor pilot directed the captain to execute a simulated three-engine ILS approach, and to expect a missed approach at the decision height. The landing gear was extended and after the aircraft passed the outer marker, flaps were placed full down (50deg). The tower cleared TWA 5787 to land. At the decision height, a missed approach was announced. The captain advanced power on engines 1, 2, and 3, and called for "25 Flaps," "Takeoff Power," "Up Gear." However, neither the flaps nor the landing gear moved from their previous positions. The aircraft was accelerated to 130 knots and a missed-approach climb was instituted. Approximately 16 t o 18 seconds after the start of the missed-approach procedure, one of the observer pilots commented, "Oh! Oh! Your hydraulic system's zeroed." At 300 feet agl and an airspeed of 127 knots all hydraulic pumps were shutdown, but power on the no. 4 engine was not restored. Directional control was lost and the aircraft struck the ground in a right-wing low nose down attitude. The Boeing 707 broke up and caught fire.

The aircraft was engaged in a sightseeing flight from Kalaupapa – Lihue, carrying 11 passengers and two pilots. En route, the left engine lost power. Unable to maintain flying speed, the crew attempted an emergency landing when the airplane struck trees and crashed in a wooded area. A passenger was killed while 12 other occupants were injured, some of them seriously.

The pilot departed Jackson-Reynolds Airport on a local test flight to check the radio systems. Just after liftoff, while in initial climb, the right engine caught fire. The pilot completed a wheels-up landing in a swamp near the airport. He was slightly injured and the aircraft was damaged beyond repair.

Upon landing on a swift river near Wenatchee, the float equipped aircraft crashed and partially sank. The pilot was rescued while the passenger drowned.

After takeoff from Hollywood-Burbank Airport, while climbing, one of the engine lost power. Control was lost and the airplane crashed near the runway end. While the passenger was seriously injured, both pilots were killed. The aircraft was destroyed.

As the crew was 12 minutes behind the schedule, he decided to start the takeoff procedure from an intersection and the departure was precipitated despite ATC warned the crew about the recent takeoff of a Boeing 707 from the same runway. Just after liftoff, while in initial climb, the airplane became unstable then stalled and crashed. Both pilots and a passenger were killed while 11 other occupants were injured, some of them seriously.
