Who killed "Dead Meat" Thompson?

The circumstances of LT “Dead Meat” Thompson’s (from Hot Shots) death are as unfortunate as they are spectacular: during a training flight he crashes into another jet whose pilot, LT “Wash Out” Pfaffenbach, is not allowed to fly. Dead Meat survives the crash without any major injuries, but down on earth at the crash site he is hit by an ambulance. His fellow, LT “Topper” Harley, carries him into the ambulance, hitting his head against the car several times. When they finally arrive at the hospital, the doctor takes a shot of rum before Dead Meat is brought into the emergency room - which he won’t leave alive. Suppose that in the aftermath Dead Meat’s widow (who will not benefit from a life insurance) sues all those responsible for his death. How should a compensation payment have been divided between all those involved?
