Crashed in unknown circumstances south of Los Angeles, killing all eight crew members. The s/n has not been confirmed.

Upon landing, the nose gear collapsed. The aircraft skidded for several yards before coming to rest on the runway. All eight crew members evacuated safely while the aircraft was damaged beyond repair.

The four engine aircraft was enroute from Great Britain to Malta. While approaching Lampedusa Island by night, the crew lost his orientation and circle for about an hour when the captain decided to ditch the aircraft that crashed into the sea and was destroyed in position 35 degrees 30 North / 12 degrees 35 East (off Lampedusa Island) at 1934 hours GMT. It appears all 15 occupants were killed. Some of them were members of the staff that was involved in the Yalta Conference.

The crew left Maxton AAF to Lubbock, Texas, with an intermediate stop in Birmingham, towing to Waco CG-4A gliders. On approach to Birmingham, the crew was vectored to the NE-SW runway but for unknown reason, the captain decided to land on the north-south runway. After both gliders landed without problems, the crew of the C-47 started to take off when shortly after rotation, the aircraft stalled and crashed in flames. All four occupants were killed.
Crew:
T/Sgt E. M. Bechtold,
1st Lt Fred T. Heise,
2nd Lt John N. Ricker,
Avc Lawrence W. Schloss.

During takeoff roll, a tyre burst. The aircraft went out of control, veered off runway and came to rest in flames. There were no injuries but the aircraft was written off.

The aircraft left Algiers Airport at 1103LT bound for Florence, Italy. Weather conditions along the route were poor with low visibility, cloud at 2,000 - 3,000 feet and snow falls. At 1506LT, the crew received the permission to descend from 12,000 to 6,000 feet towards Florence. As the aircraft failed to arrive, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. It is believed the aircraft may have crash into the Ligurian Sea or on a mountain located somewhere in Corsica.
