This collision happened precisely because of unfortunate circumstance that break in the rail and derailment happened just before the switch leading to the opposite track. Without the "help" of the switch, carriages of the first train likely wouldn't have invaded the second track.
You cannot operate fly-by-wire aircraft without computers, that's what I meant. Redundancy is name of the game, I see no problem in using cameras if they're made redundant.
This seems bit excessive, Concorde booms were purportedly about 105-110 dB on the ground when cruising at altitude (around 60 000 ft).
I've personally only experienced sonic booms from MiG-21s. They are not painfully loud, but surely startling. They are very deep and make the windows rattle.
To be fair, they do need an alternate with a better visibility. But if the computers are not working, you're not in for a good time in a modern airliner anyway.
Tsar bomba was 100 Mt design, about 50 Mt test. Not much of a difference, you're going to be toast anyway (multiple "smaller" warheads are more economical and harder to intercept anyways).
> YAML has a lot of extra stuff going on that can cause accidents if you don't take care. The classic example is the "Norway problem" where "no" (the country code for Norway) is parsed as "false" instead. If "no" is used as a key, this can cause the Norwegian data to disappear or to throw strange errors on load.
This was fixed in YAML 1.2, but the problem is that almost nobody uses (and there is patchy support for) it.
