Frank Eugene Corder
Frank Eugene Corder (May 26, 1956 – September 12, 1994) crashed a stolen Cessna 150 onto the South Lawn of the White House early on September 12, 1994, apparently trying to hit the building; he was killed, and was the sole casualty....
....He stole the Cessna on the night of September 11 and departed from Aldino Airport in Maryland severely intoxicated, which is presumed to have led to his later miscalculation. The plane was noticed by radar technicians at National Airport several minutes before he tried to steer it into the wall of the White House. At 1:49 a.m., he hit the South Lawn and died on impact.
The crash caused a re-evaluation in security procedures around the White House, as the pilot had entered restricted airspace. Though the White House is rumored to be equipped with surface-to-air missiles, none were fired. The Secret Service has neither confirmed nor dispelled the rumor.
