Gatwick Airport briefly suspended all outbound flights around 09:00 today (April 13 2012) due to a hot-air balloon straying into its airspace.
Gatwick Airport Disruption Reports
Incoming planes were not affected and flights quickly resumed as the balloon drifted away.

We also saw the first flight, EasyJet EZ8917 (EZY8917), departing Gatwick at around 09:15 shortly after the balloon was safely out of the area.
