Fire just got put under control in the last ten minutes, but had been burning for 40 minutes.
Available 3-18-2010, 1900-1930 UTC. at 5:00 into the clip, a departing flight tells tower they're "pretty sure there's a fire in a hangar." Otherwise its a quiet frequency.
EDIT: Tower controller mentions it looks like the fire was at Infinity Aviation, an FBO on the grounds. No injuries.
