One of Avianca's Fokker 100's had to perform an emergency landing in Brasilia. The pilot touched the ground with the aircraft's back wheels - the front wheel assembly failed to work properly - and kept its nose up until it slowed down a bit so there would be less friction when using the plane's "belly" to accomplish the landing. Firetrucks were there to spray some foam while the plane slid through the ground to avoid grater explosion risks. Experts said "the pilot was extremely careful and performed each and every measure provided by the Pilot's Manual. He kept the plane flying long enough until there would be a small amount of fuel left and communicated with the passengers and the tower very clearly and calmly."
