The American airport where a passenger plane and an army helicopter clashed is a difficult airport to land on. In Washington DC there are two important airports: Ronald Reagan Airport, who mainly facilitates domestic flights, and Washington Dulles International Airport, which mainly facilitates foreign flights. On Ronald Reagan Airport there are three runways, but only one of those three is long enough and therefore safe to land. To be able to do that, the pilot must take a number of sharp turns. There are a few zones where an aircraft should not be due to safety reasons. In addition, the airspace is heavily overloaded, so many feared that it once went wrong.
