During your tour of an airport, you've just entered the control tower when a loud crash and a scream is heard in the hallway.  Your tour guide and the air traffic controller run from the control room to see what happened.  Unfortunately for you, the control tower door closes and latches!  You're locked in the control room and the air traffic controller is NOT! (and the door cannot be opened from either side... for now).

 

Radio calls are heard from aircraft approaching the airport requesting landing instructions.

 

You must (1) gain access to the air traffic control consoles, (2) provide landing instructions to the aircraft and (3) locate the emergency procedure to escape from the control tower (which you'll want to do promptly if any of the aircraft crashed).
