Test

The crew left RAF Brawdy in the evening on an experimental night radar meteorological research flight. Aircraft was due to overfly a marker dropped into the sea taking readings at 100 feet intervals up to 1,500 feet using a radar altimeter to secure accuracy. At 0200LT, while descending to 200 feet, the aircraft impacted the sea. No recovery of bodies or wreckage proved possible. Aircraft and crew were from the RAF Radar Meteorological Flight based at Defford, but detached to Brawdy for this particular sortie.

The crew was involved in a test flight on this Martin JRM-3 Mars christened 'Hawaii Mars'. While cruising at an altitude of 6,000 feet, severe vibrations forced the crew to reduce his altitude in an attempt to make an emergency landing in the Chesapeake Bay off Virginia Beach. On landing, the seaplane partially broke up and nosed down in water. All ten crew members were rescued and the aircraft was later recovered but considered as written off.

The seaplane left Mokerang Airfield at 0330LT to test the distance measuring equipment for COMAIR Admiralties. As the aircraft failed to return, SAR operations were conducted but were eventually suspended few days later as no trace of the aircraft nor the 12 occupants was found.

During a test flight, control was lost and the aircraft crashed in Meltham Moor, near Meltham. The aircraft was destroyed and all five crew members were injured.

The crew was engaged in a test flight at Wright-Patterson AFB. Shortly after takeoff, in initial climb, the twin engine aircraft went out of control and crashed in a huge explosion in a hangar. Many explosions occurred, the hangar was destroyed as well as several aircraft, including a Consolidated B-32 Dominator registered 42-10873, a Douglas C-47A-10-DL registered 42-23357 and a Boeing B-29 Superfortress registered 42-63598. All three crew members and five employees in the hangar were killed in the accident.
Those killed were:
1st Lt Elwin I. Brawner Jr.,
Pfc Eugene L. Fisher,
2nd Lt Robert E. Jackson,
Pfc John L. Ravegum,
Pvt Browder A. Richmond,
T/Sgt Russel P. Schryer,
Sgt Albert B. Weathers,
Sgt William W. Wilson.

The seaplane stalled and spun into water some 10 miles south of Beqa Island, while operating with No. 6 squadron. During a post maintenance test flight, the aircraft was deliberately stalled at 5,500 feet but entered an uncontrollable spin and dove into the sea near Beqa Island. Four crew and eight passengers were killed while two crew and four passengers got clear of the wreckage before it sank and survived.

During the day, technical anomalies were noted on the engines and the captain decided to perform a test flight. The twin engine aircraft left Richmond Airfield at 1620LT. Ten minutes into the flight, the captain informed ground about technical problems and elected to return to the airport. On final approach, while at a height of 200-300 feet, the left engine failed. The aircraft banked left, hit power cables and crashed in a huge explosion some 400 yards short of runway threshold. All eight occupants were killed.

The crew was engaged in a test flight off Koror. As it prepares to land, the seaplane hit the water surface and came to rest. Both pilots were rescued while both other crew members, the radio navigator and the flight engineer, were killed.

The crew was performing a circular test flight following maintenance and left RAF Wendling shortly after noon. After a first circuit completed uneventfully, the aircraft was approaching the airfield and while crossing the last cloud layer, at a height of 300 feet, the number three engine failed. Despite several correction on part of the pilot, the aircraft became unstable and the crew attempted an emergency landing when the left wing hit a tree. Out of control, the aircraft christened 'Flying Crusader' crashed in flames in a field. As four crew members were injured, the radio navigator was killed.
