Narrative:
Texas International Flight 987, a McDonnell Douglas DC-9-14, crashed after rejecting a takeoff from runway 8R at Denver-Stapleton
International Airport, Colorado. The takeoff was rejected when the stall warning stickshaker activated after the aircraft had rotated
for takeoff. When the pilot was unable to stop the aircraft within the confines of the runway, it overran the runway, traversed drainage ditches, struck approach light stanchions, and stopped.

Probable Cause:

PROBABLE CAUSE: "A malfunction of the stall warning system, for undetermined reasons, which resulted in a false stall warning and an unsuccessful attempt to reject the take-off after the aircraft had accelerated beyond refusal and rotation speed.
The decision to reject the take-off although not consistent with standard operating procedures and training, was reasonable in this instant case, based upon the unusual circumstances in which the crew found themselves, the minimal time available for decision, and the crew's judgment concerning a potentially catastrophic situation."
