Here is the full video of the Ethiopian Airlines Flight 302 which took off from Addis Ababa to Nairobi and crashed killing 157 people.
Investigations indicate that shortly after V1 speed (V1 is the speed beyond which take-off can no longer be aborted) the crew experienced difficulties and requested permission to return to the airport.
The flight 302 was climbing out when the aircraft leveled out at about 9,000ft above sea level. Radar contact was lost about 6 minutes later. The picture of the crash site indicated a high speed impact with the aircraft disintegrating when it hit the ground, and post crash fire.
Flight radar 24 was able to capture the first 6 minutes of the aircraft’s ADSB (Automatic Dependence Surveillance Broadcast) data as the aircraft departed to the east.
The standard instrument departure to the east requires the aircraft to be at 12,000ft but it was at 9,000ft. This indicates that the aircraft was below the desired altitude, thus putting the aircraft within 1,000ft of the mountainous terrain.
The aircraft rolled out on the runway and climbed into the sky at rate of 2,000ft per minute, and it quickly drops off to ZERO ft per minute, followed by another positive climb and another negative descent of 2000ft per minute, followed by another positive climb to about 7,000ft in 3 minutes before losing contact with the radar.
An altitude of just 1,000 to 2,000 feet above the ground, gives the crew very limited time and space to react if there is a controllability problem.
