Circumstances:
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.
Probable cause:
It was determined that the crew lost control of the airplane due to wake turbulences caused by a Boeing 707 that just took off from the same runway. The crew failed to consider the warning from ATC.
