Bangor is the first major American airport encountered by airliners approaching the United States from the east and the last for airliners heading towards Europe. With a runway that is more than two miles (3.2 km) long and an uncluttered airspace, it offers a place to land in case of bad weather at an airplane's destination, bomb threats, or passengers who prove unruly or are discovered to be on the Transportation Security Administration's No Fly List. Between 2004 and May 2012, the airport handled 647 unscheduled landings: 388 for fuel, 139 for weather, 50 for medical reasons, 49 for maintenance problems, and 21 for security reasons. Because of its experience, the airport is able to quickly assemble firefighters, ambulances, police officers, and federal agents to meet such planes. During their involuntary visit to Maine, passengers receive food and donated cell phones to make calls. The airport receives $2,000 to $3,000 in handling and fuel fees, so it makes a small profit for each diverted flight.
