1) Autonomy oxygenates some (mini bottles hung on the sides of its parachute) is 48 minutes after the jump of the stratospheric balloon. What represents approximately 6 minutes 30 of free fall plus 5 minutes under veil. The rescue team must be ready to react constantly in a minimum of time (less than 30 minutes). If unconscious, must open the visor of his diving-suit to him so that it can breathe.
2) have helicopters with possibility of in the case of jumping a landing on a woodland, or a water level. Equip with a combination neoprene, have a small sheath in which the material of first aid is fixed on the strap of chest of my parachute. The jump rescue will be made rather low to arrive quickly on the ground. The drift can go from 50 to 300 Kms (approximately) compared to the base of launching of the stratospheric balloon by the fact of the wind in altitude “jet stream”.
