This Unicode gripe is almost as bad as the anti-aliasing gripe you used to hear from Linux people. I guess Linux has anti-aliasing now, because I haven't heard that one in ages. You know what? I hope they *never* get Unicode on Slashdot. What would we do with it? OK, the occasional accent grave or umlaut is nice, but all the emoticons that come along for the ride just aren't worth it. Yeah, they could filter it, but whatever. Slashdot without unicode is just fine. Slashdot without stories is nothing.

HUGE amount of force trying to crush the tube. 14 lbs/ square inch.

The Transbay Tube has a maximum depth in water of 41m, and according to this calculator experiences 74.4696 psi at that depth.

The tube liner by itself would probably have no trouble handling the pressure. It will almost certainly be surrounded by steel-reinforced concrete or at the very least pipeline steel because building such things is well understood. However it's built, it'll be ridiculously over-built if an M-80 or a rifle is the biggest threat. A real terrorist IED is always a threat of course, but no more so than for traditional rail.
