If you think that's bad
I had a friend on my computer course at uni who ended up doing process control in UK nuclear reactors...
I remember a C4 documentary on the telly in the '90's rumouring poor software, so I called her up.
She not only confirmed it, but said there was "far worse" going on!
If a 747 crashes, that's 400-500 people's lives, but if a reactor goes up.....
