Takeoff (climb)

Shortly after takeoff from São Paulo-Congonhas Airport, while in initial climb, the pilot-in-command encountered problems and lost control of the aircraft that crashed onto several houses located in the Jabaquara neighborhood. On ground, someone decided to light candles in order to get more light when the fuel that flowed to the ground ignited. Few explosions occurred, killing all ten occupants inside the aircraft and six people on the ground.

The crew was completing a local training flight at Mountain Home Airport, consisting of touch and goes. After takeoff, while in initial climb, the four engine bomber went out of control and crashed in a huge explosion about 1,300 feet past the runway end. The aircraft exploded on impact and disintegrated, killing all seven crew members.

Shortly after takeoff, while climbing, the airplane went out of control and crashed 400 meters past the runway end. All four crew members were killed.

After takeoff from an area located along the Lena River, in the region of Yakutsk, while climbing to a height of 50-60 meters, the single engine aircraft banked left to 65° and nosed down to 25° then plunged into the Lena River about 200 meters offshore. All four crew members were able to evacuate the cabin but only three reached the shore as the flight engineer was drowned.

Crashed on takeoff. Crew fate unknown.

The crew (three engineers and pilots from Boeing and three USAF officers) were engaged in a local flight from Seattle-Boeing Field to test the airplane that was subject to technical modifications. Shortly after takeoff, while in initial climb, the four engine airplane encountered serious difficulties to gain height when the right wing hit the roof of a brewery located about a mile north of the airfield. Out of control, the aircraft stalled and crashed in a huge explosion on the Lester Apartments building. The airplane was destroyed by impact forces and a post crash fire fed by 4,000 gallons of fuel. All six crew members and five people in the building were killed while 11 other people on the ground were injured. The exact cause of the mishap remains unclear.
