A skydiving student has difficulty regaining a controlled, stable body position shortly after exiting the plane. As he deploys, the pilot chute wraps under his body, causing a pilot chute in tow.
According to the person who submitted this video, instead of the student pulling his reserve, he "waited for the pilot chute to work."
Watching this video will make your palms sweat (or make you feel sick), but luckily the student was saved by his AAD (Vigil 2), which opened his reserve just under 1,000 feet. Phew!
