MOSTAFA, what connection are you making between a five year old newspaper article and a training accident 40 years ago?
Probably that a Calculated Air Release Point error, whether due to unknown wind changes or any other reason resulted in Para deaths.
I was on exercise, in an Argosy, in Libya, when a Herc dropped off DZ at night resulting, I was told, in one death and some injuries. Recollect thinking, at the time, that, in an exercise, one can always ask for a white flare from the DZ Officer.
