Word to the wise: If you’re flying over DC, make sure your transponder is working.
The top general at the North American Aerospace Defense Command was on the telephone and prepared to order an F-16 fighter to shoot down an unidentified plane that turned out to be carrying the governor of Kentucky to former president Ronald Reagan’s funeral last month, according to two federal security officials briefed separately about the incident.
The tense incident June 9 ended after the twin-engine Beechcraft King Air carrying Gov. Ernie Fletcher (R) turned to land at Reagan National Airport. But the close call caused officials to reassess safeguards for the airspace around Washington and prompted calls to expand the no-fly zone beyond its current 16-mile radius.
. . .
On June 9, the Beechcraft King Air was flying with a broken transponder, a device that transmits an identifying signal picked up by ground controllers. After takeoff, the pilot, as required, notified Federal Aviation Administration officials in Ohio about the problem at 2:56 p.m.
But the FAA failed to notify military and homeland security officials, who monitored separate radar displays, about the broken transponder. To everyone but the FAA, radar showed an unidentified intruder entering restricted Washington airspace at 4:24 p.m.
At 4:31, with the plane a minute or two from downtown Washington, officials ordered the evacuation of the U.S. Capitol, where thousands had gathered to await the arrival of Reagan’s coffin. The FAA reported to air defense authorities that it was in contact with the plane three minutes later, as the aircraft made the final approach to National Airport.
The Beechcraft was traveling at roughly 240 miles per hour, or four miles a minute. At that speed, it could have reached the center of the no-fly zone in four minutes.
