Tangled parachutist dies in OZ accident
According to BBC Ceefax (Page 118) a parachutist died when his chute became tangled round the tail of the aircraft when he jumped. This is stated to have caused it to go out of control and the crew and the other skydivers saved their lives by using their chutes for serious not sport purposes and jumped and saved their lives, the tangled man being killed when the otherwise empty aircraft crashed near Sydney.
I cannot see that the survivors can be blamed in any way as there would have been absolutely no point in their trying in vain to release him and all dying as well.
