I did not understand completely what was going on w that water crash, maybe having mechanical issues and could not lift? Terrifying, anyways.

A friend I grew up with is a former Navy Seal Team diver and he worked at Ft. Benning in the "dunk tank", (not sure if that's the proper name). It's the armed force's state-of-the-art facility where they dunk a helo cabin into water and invert it, he taught under water survival/escape from it. Sounds like what you describe, Don, was it there?
