Metro International Airport

Metro International Airport is the setting for the fourth level in the campaign Dead Air.

History
Before the infection, the airport was one of the many ways out of Newburg, but as the infection started to spread throughout the city, the airport may have been shut down and converted for evacuation of citizens by CEDA and Newburg police, but by the time the Survivors arrived to be evacuated, the airport was already bombed by the military and completely overrun. The Survivors arrived just in time to watch a plane seemingly try to land, but the pilot appears to have become infected or had simply died and promptly crashed and exploded on the runway, causing flaming wreckage and debris to hurtle towards the unsuspecting Survivors.

Having seen what appeared to be their savior die in a most unsavory manner, the Survivors escape the airport in a Lockheed C-130 Hercules of Korean design.

Current Status
Metro International Airport has been largely destroyed by the plane crash, but it is possible that the airport, along with the rest of the city, may have been bombed. This is supported by the fact that the military were seen bombing Infected in Left 4 Dead 2 and that the Survivors will occasionally comment that the airport was bombed.

Trivia

 * After the debris settle down, it can be noted that there does not appear to be any bodies in the wreckage, though it is possible they were simply vaporized in the blast.
 * Though many believe that the pilot(s) became infected, the jet seen crashing is heading directly for the runway, something that the Infected would not understand, much less attempt. A more probably explanation is that several of his/her passengers had became Infected and started attacking pilot, making the plane lose control during the struggle. However the tight turn and poor angle is something a real pilot would never think of attempting, so it's possible that an unskilled person was flying the airplane and was unable to safely land due to lack of experience.
 * Strangely enough, the plane that crashes in the Runway Finale is unlike any other plane in the airport, perhaps belonging to another airline.
