American Airlines Flight 444

American Airlines Flight 444 was a scheduled American Airlines flight from Chicago to Washington, D.C.'s National Airport. On November 15, 1979, the Boeing 727 serving the flight was attacked by "the Unabomber", Ted Kaczynski, who placed a bomb on board. The bomb, planted in the cargo hold, caused "a sucking explosion and a loss of pressure," which was then followed by large quantities of smoke filling the passenger cabin, forcing the pilots to make an emergency landing at Dulles International Airport.[1][2][3] Twelve passengers had to be treated afterward for smoke inhalation.[2] It was later determined that the bomb was powerful enough to have destroyed the aircraft if it had worked correctly.
