Something I've been wondering for a while (don't ask me why, I think about a lot of random stuff haha.) What are the ways ATC alert the airport's Fire and Rescue Service to an aircraft incident? If a controller sees an aircraft on fire, overrunning the runway etc, is there an alarm/panic button that can be hit to alert the fire station? And do they simply ring on a phone to give details, like incident location, type, aircraft involved etc? Are there standard procedures or does this vary from airport to airport?
