^^ I recall a few years ago reading about the dive by David Shaw et al at Bushmans Hole in south africa in Outside magazine. It was truly a mind blowing story. THe cave is 900 feet deep.

You know the wingsuit guys flying around the alps in recent videos? This story makes wingsuits seem pretty controlled and safe!

Anyway, sorry for the OT-
