Can we assume, the aircraft weight had nothing to do with the end result unless it was a proven direct link in the chain of events. The only link I can think of is low and slow and lack of response to any power input. But then again, was the aircraft at full throttle at impact?
Try Quirindi for a winter time black hole approach. Try then a take off from the same aerodrome, same time, into nowhere except blackness.
Recency is the key word.
