For me, it would have to have been the trip to Glasgow in June 2004. Myself and Andy (A330Crazy) flew up to Glasgow from Heathrow with bmi. Unfortunately, it was just our luck to find that an air traffic control system crash was causing lengthy delays and cancellations to the majority of all domestic flights.
We sat at Heathrow for a few hours, listening as different airlines announced that particular flights were being cancelled and really expected ours to be, too. However, it didn’t get cancelled and did eventually depart for Scotland, albeit 90 minutes later than scheduled.
We arrived in Glasgow where Allen (Ren Frew) had been waiting for us and trotted round to the mound where we enjoyed the views for a little while before being stopped and questioned by police. They asked for identification from all of us and then got onto their radios to check that we weren’t terrorists. How embarrassing!
