Not quite at the same level, but in the 90's I was doing work for a company that was in the process of building a satellite communications network (it never saw the light of day - they ran out of money long before they were ready to launch their first satellite). My responsibility was with a part of the ground network system. One week I (plus my boss in that company and few other people) flew out to Japan to visit the ground segment prime contractor; it was a sort of multi-function visit, with my job being to witness and sign-off factory acceptance tests for the part of the ground segment that I was responsible for. This was scheduled as a two-day job, with me returning to the UK at the end of it. The first day started OK and the morning tests proceeded fine. After a break for lunch, testing resumed and things went distinctly runny - a test aimed at proving some critical functionality failed completely and pretty spectacularly . Nothing I could do; I just stepped back and watched quietly while the prime contractor's minions rushed about trying to work out what was wrong, and management bodies panicked.
I reported this to my boss in the evening, only to be told that I would have to stay in Japan as long as it took; we had to sign things off to keep to the schedule, and if that inconvenienced me then so be it. I have to admit, I was not a happy bunny at that prospect!
The next morning, I rolled in to he prime contractor's sight to be greeted with smiling minions and management - they had found the problem at 2:00am (it turned out to be a small error with big consequence - they had not purged an old configuration before starting the test, which meant that the equipment was in a very odd state). They thanked me for me patience and understanding the previous day (nice to be appreciated) and we cracked on with the testing. We managed to get it finished in time for me to get to the airport and catch my scheduled flight home, with me filling in my paperwork on en route and faxing it to them the next working day.
