Incident Overview
A Continental Airlines aircraft overran the runway after touching down approximately 2,500 feet down a wet, downhill runway. The captain had executed an Instrument Landing System (ILS) approach to Runway 11.
Approach and Touchdown
According to Continental Airlines, the captain used a reference airspeed (Vref) of 136 knots during the approach. Flight data recorder information indicated that the actual airspeed fluctuated between 150 and 159 knots during the final phase of the approach. The aircraft touched down about 2,500 feet beyond the runway threshold.
Braking Procedure
The captain stated that after touchdown he deployed the thrust reversers, followed by the speed brakes. The procedure taught to Continental pilots was to deploy the speed brakes first, and then the thrust reversers, in order to achieve maximum braking effectiveness.
Outcome
The aircraft overran the runway. No further details on the extent of damage or injuries were provided in the source.
