I thought it was universally agreed that green would be used for sarcasm @ PPOT.

Then take the other hull to the Titanic and lower and raise the hull at least 100 times.

Rush made the mistake of taking short cuts and if I can quote JRR Tolkien; Short Cuts Make Long Delays

I haven't watched the various videos posted in this thread about the sub or its construction, but I thought I'd read that the sub had been down at least a few times before. And based on discussion here (and it makes sense to me, but then I don't have expertise in c/f or materials science. It sounds like a big part of the problem may not have been a single trip down, but that repeated trips, multiple pressure cycles could have caused tiny flaws to create issues that increased/multiplied over time.

For instance, maybe if every trip down was a brand new sub, it would have been (relatively) safe, but taking the same sub down multiple times was destined for failure.

Clearly, there were lots of issues with the thinking/design/implementation, and I wouldn't want to be in the thing at any depth (what's the point with 1 tiny view port).
