It was both my Mk15.5's, neither were recoverable
Actually, I was damn near killed by a KISS valve!!! Flew past my ear and exited via the passenger window as did a 7l bottle of O2 and a Poseidon 1st stage, a pair of jetfins and my AUL cannister light. I'd read a thread somewhere before (not sure if it was on YD or somewhere else) about the dangers of bringing dive kit to a sudden stop and thought it was a bit of an over-reaction. I guess not, heavy bits of kit must really have a lot of momentum.
Also made me wonder how much time they spent choosing the colour of air bags. When it happened my whole world went a pretty sky blue, very peaceful and calm, I thought I was dead and thought it wasn't so bad. When I woke up I realised it was just the airbags going off that had filled my vision. Excellent colour choice. If I worked in the factory, I'd love to stencil "TWAT" on the airbag before I packed it
