This situation escalated quickly, from a simple angle jump to two skydivers being knocked out in freefall.
The girl in the white jumpsuit lost control and hit another skydiver in the back of the head/neck. She got knocked out for the duration of the jump and was saved by her AAD (CYPRES).
The "victim" who got hit was also knocked out, but he regained consciousness in freefall and deployed his parachute to land safely.
They're both incredibly lucky not to have been paralyzed or seriously injured from this incident.
