The White House, U.S. Capitol and other government buildings were briefly evacuated today, Wednesday when a small plane entered restricted airspace around Washington.
A White House spokesman, Scott McClellan says that at its closest point, the Cessna aircraft was about five kilometers away from the White House. He says the pilot did not communicate with aviation officials or three aircraft sent up to intercept the plane.
The Cessna eventually turned away from the city and was escorted to a landing strip north of Washington in Frederick, Maryland.
Capitol building Police Chief Terrance Gainer says two men aboard the plane have been taken into custody for questioning.
President Bush was away from the White House at the time of the security alert.
U.S. officials have been extra vigilant about possible attacks by planes since the September 11th, 2001 terrorist attacks.
