Boeing B-17 Flying Fortress

Aircraft took off from Clovis Army Air Field in New Mexico, bound for Hamilton AAF in Marin County. The plane stopped at Mines Field in Los Angeles, refueled, retook to the skies at 2317LT and was due to arrive at Hamilton at 0117LT in the morning, but the pilot, according to the Army investigation, lost his way while trying to locate Hamilton Field. At around 0200LT in the morning, and five minutes from its destination, the pilot radioed Hamilton Field for radar assistance in landing. But, shortly after 0200LT, the engines of the bomber, starved of fuel, quit, and the bomber smashed into a 1300-foot peak of White's Hill, some nine miles short of the airfield. Striking the hill only six feet below its top, the plane bounced over the top, thudded across the rough terrain, and slid to a grinding halt that churned up earth and rock for more than 100 yards, and scattering wreckage for 300 yards. Dazed, confounded, and startled by the crash, the pilot and co-pilot extricated themselves out of the wreckage of his once-proud aircraft. Still trapped in the wreckage were five of their crew. Stumbling and clawing their way through the morning darkness towards the city lights they saw in the distant, they reached a retirement home, from which they alerted the airfield. Killed instantly in the First Lieutenant Milton M. Souza, 25, of Santa Clara. CA. and Master Sergeant E. B. Nichols, of Clovis, NM. Rescuers chopped a hole through the wreckage with an axe to extricate a Lieutenant Colonel from the fuselage. He was then strapped on a litter with his parachute shrouds and brought down the hillside. It took a total of six hours to free the five trapped men from the plane, two of whom were seriously injured.

On landing, the four engine aircraft went out of control, veered off runway, went through the apron and collided with a parked RAF C-47 registered KG427. There were no casualties but both aircraft were damaged beyond repair.

Crashed in unknown circumstances in Praia de Muriú, near Natal, killing all seven crew members.

The crew was performing a flight from England to Lyon-Bron Airfield. While approaching Lyon from the west, the crew encountered poor weather conditions and low visibility due to the night. Suddenly, the four engine aircraft christened 'Blinkin Betsy' stalled and crashed in a field located in Saint-André-la-Côte. All three passengers and two crewmen were killed, three others were seriously injured.

The flight was scheduled from Prague to Stockholm-Bromma direct but while approaching the Swedish coast, the crew was forced to divert to Göteborg Airport due to poor weather conditions. All passengers disembarked in Göteborg and the crew continued to Bromma. On approach, the aircraft was too low and hit a wooded hill located in Stallarholmen, about 40 km west of the airfield. The aircraft was destroyed and all six crewmen were killed.

Enroute, while cruising along the Italian shore, the crew encountered poor weather with severe icing conditions and told ATC he wanted to divert to Rome Airport. Later, while in poor visibility due to clouds, the aircraft hit the slope of Monti della Meta located few km northeast of the Picinisco village. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. The wreckage was located by walkers in May 1946. It is believed that the crew misjudged the icing severity and the flight was not properly prepared. Heavy cumulus were present from 1,200 up to 5,000 meters.

The crew was performing a humanitarian flight from Ottawa to Warsaw, Poland, with an intermediate stop in Prestwick, carrying a load of pharmaceuticals consisting of penicillin. En route over Germany, crew encountered poor weather conditions with cloud layer till 1,000 feet. Captain decided to fly below the clouds when the aircraft hit a tree and crashed. All five occupants were killed.

On approach to Grenier Field AFB, Manchester, the crew was hampered by poor visibility caused by night and low clouds. The aircraft crashed in a dense wood area located three miles south of the airport. Three crew members including Sgt Earl K. Allen. Two others survived, F/O William J. Anderson and Sgt Charles R. Jones.

The aircraft was on its way to the US with Army personnel on board. About an hour after departure from Pomigliano Airbase, an engine failed, forcing the crew to ditch the aircraft into the Tyrrhenian Sea. On impact, the aircraft broke in two and sank in 30 seconds. Twelve hours later, twelve people were rescued while 13 others were killed. A body was recovered on the Italian coast over four months later, some 300 miles from the crash site.
