You may be correct in your thoughts of surviving a roof chute leap on 911.
Tho
Helicopter flying conditions are not indicitive of the ability to parachute in those same conditions.
Then again I bet 100% of the people who died would rather have burned in with a chute than in a rubble pile.
The memory of people leaping to their deaths (with no chute)to avoid the flames is something I will take to my grave.
