The Learjet 55 was in the air for a brief 60 Seconds before disaster struck. While some communication had occurred, there were no reported issues with the control tower. The plane crashed near Roosevelt Blvd after a 60 second flight.

The crash was caused by a fireball that resulted in a big blast, leaving buildings in flames and buildings damaged.  Firefighters had to put out a large fire. Several structures were ablaze.
