In ~1997 I got stuck in a huge traffic jam on the way to Heathrow airport. I arrived about 15 mins before my UK->USA flight was to leave. At the check-in desk I handed them my extremely worn passport and the photo just fell out of the back page as they took it. They were like "Er, hold on a sec" and disappeared for a min. Then they came back, handed me the passport and the photo and said "RUN! YOU CAN MAKE IT!" and I did.

Wild times. Planes still had their ashtrays then too.
