Safety and aviation officials said Wednesday that two airliners landed at Reagan National Airport near Washington without control tower clearance because the air traffic supervisor was asleep.
An aviation official says the the supervisor had fallen asleep. The supervisor was the only controller scheduled for duty in the tower around midnight Tuesday when incident occurred
The official spoke on condition of anonymity to discuss the incident.
The National Transportation Safety Board spokesman Peter Knudson says the NTSB is gathering information on the occurrence to decide whether to open a formal investigation.
Knudson says the pilots of the two planes were unable to reach the tower, but they were in communication with a regional air traffic control facility. That facility is in Warrenton, Virginia, about 40 miles from the airport.
He says the planes involved were American Airlines flight 1012 and United Airlines flight 628T.
