In June 2004, Fletcher's aircraft caused a security scare that triggered a brief evacuation of the U.S. Capitol and Supreme Court building. Shortly after takeoff en route to memorial services for former president Ronald Reagan, the transponder on Fletcher's plane malfunctioned, leading officials at Reagan National Airport to report an unauthorized aircraft entering restricted airspace. Two F-15 fighters were dispatched to investigate, and Fletcher's plane was escorted to its destination by two Blackhawk helicopters. The plane, a 33-year-old Beechcraft King Air, was the oldest of its model still in operation. An investigation by the Federal Aviation Administration (FAA) found that the crew of Fletcher's plane maintained radio contact with air traffic officials and received clearance to enter the restricted air space. The investigation determined that miscommunication by air traffic controllers sparked the panic, and in the aftermath of the incident, the FAA adopted policies to prevent future errors of a similar nature.
