I was wearing an Eastern Aero Marine, dual chamber, manual inflatable aviation lifejacket. Unfortunately, upon my inquiry, it was discarded after being cut from me in the ambulance. I was told by my fellow firefighters that it had been ripped open. But, even damaged, it saved my life.
There's more to say about the accident, but that will have to wait. All I can say is that it occurred during an intended water landing.
