Soldiers were actually surviving the impact during helicopter crashes but needed more time to get out. Egress times to survive: Large transport planes - 90 seconds Helicopters - less than 17 seconds to make it outside the fireball Auerbach, M., Ramsay, J., D’Angelo, P., Cameron, S.,Proulx, G., Kaplan, J., Grady, M., and Coyne, M.
