The aircraft, McDonnell Douglas MD-82, is a T-tail aircraft. T-tails have poorer stall characteristics than aircraft with conventional tails/stabalizors and wing mounted engines.

Given the fact that the explosion happend very short after takeoff, the time during flight where the alpha is the highest, the loss of one engine would have incresed that alpha and gone into a stall which, with the little altitude, could have been unrecoverable. This is just my speculation though.
Another spectulation; Could the hydrulics been damaged by explosion/fire and cuased the plane to bank right :huh:
Whatever the cuase, may they RIP... :cry:
