Synopsis

Below is an extract from the official Report by National Transportation Safety Board (USA) (NTSB) on the Serious Incident:

"The tower controller had cleared AWE83 (A320) to land on runway 10 and AWE83 was approximately 6 mile on final approach when the ATC local controller cleared COM5412 (CRJ1) for takeoff on runway 15R. COM5412 was on taxiway A about 500 feet short of runway 15R when the takeoff clearance was issued. Airport Movement Area Safety System (AMASS) alerted. COM5412 rotated at taxiway F and over flew AWE83, at the intersection of runways 10 and 15R. The initial report from the Federal Aviation Administration stated that COM5421 over flew AWE83 by 300 feet. AWE83 exited runway 10 at runway 22.
