Note the unusually steep angle of the plane from the video.
• Too steep a climb so soon after takeoff
• Restraining devices give way and armoured cars move inside plane
• Wrong CG
• Plane got engine problems
• Suicide intruder hiding in plane killed the pilots.
Today there was another US military transport C-135 plane reported crashed after taking off from Kyrgyzstan.
This may be a new pattern of attack on US military transport planes.
