I love revisiting these vintage posts. From all I've read and talked to people in the know, the Ti issue is if you have a flash fire in a first stage. that can and does happen when you "slam" open a tank valve and the high pressure gas fills the space and closes the first stage seat. the temperature in that tiny space goes sky high. it can at high O2 levels burn o-rings and any lube that's present. If the body of the first stage is made of titanium the potential is there to start a titanium fire. if that happens lots of bad things can ruin everyone's day.

Each wreck has a tale to tell about its life and its demise.
If you are observant while diving in dark places listen to the account each has to tell, You cannot come away unaffected.
