The best part of it was, that 3 years prior I'd gone into work at 6am one Saturday morning only to find a hard drive had failed, I called the boss and he made it clear that it had to be fixed by Monday morning despite me having some nice VIP tickets to the International Air Tattoo (wage negotiation preceeded, lol).
Being a weekend we struggled to get the parts we wanted but never the less I met the other engineer with the parts on Sunday, we did the job but things didn't go as planned and he ended up fudging the job so that it'd hold out until we could come up with a solution, it never did get fixed and it wasn't until 3 years later in the 9th hour of running tests and scratching my head that he finally called me to say, "Do you remember when..."
I did my job and then left him to it only to get called back in on Sunday nearly missing the England vs Germany game and yes the ball did cross the goal line!
