Sorry. The death scene and the fact that a star ship can withstand ocean pressures does nothing for me. Remeber when Trek was about science?
No, I really don't remember when Star Trek
was about real science. At least, not in my lifetime (I was born in 1971).
A construct that can survive getting close to stars and survive the wear and tear of going 0-to-Warp 5 in a few seconds should be able to handle a little water pressure. That's what the 'structural integrity field' is for.
