Not quite the same distance
But once I had to fly from London to Edinburgh at the crack of sparrows, whilst quite phenomenally unwell, hire a car, and drive a couple of hours north in order to install some software. Said software ONLY worked on Windows 2000. Not XP, not ME, not Linux, only Windows 2000.
The customer had to get a new PC to run this, so I checked three times with them that they had got Windows 2000 on it. They assured me their local specialist had indeed installed Windows 2000.
After a lovely short flight that I spent puking in the plane bathroom, and then a very lovely drive through some very nice scenery, punctuated by more puking, I arrived. You already know it wasn't running 2000. Instead it was running ME because "it's basically the same thing, but cheaper".
So I turned around and went home again. By this time I'd finished puking so it wasn't all bad.
