What's it like to pass out from hypoxia in freefall? Well, it starts with 5 skydivers at 22,000 feet and only 4 oxygen masks. Those numbers just don't add up.
After exiting the plane, one of the skydivers becomes unconscious in freefall; his 2 friends have to stabilize him and deploy his main parachute. When he landed, he told his friends that he woke up under canopy!
A situation like this could've easily been avoided had there been enough oxygen masks for all 5 skydivers. The effects of hypoxia are serious and can happen without you even knowing, so please be careful and stay aware of what can happen on high altitude jumps.
