On a flight between Osaka and Tokyo, the alarm system blares out a warning: a stabilizer has blown off and the plane can no longer steer. 30 minutes later it hits Mount Osutaka in the worst single aircraft accident in history.

An explosion jolts the pilots of PA 434; a bomb has gone off and there's extensive damage to the plane. The blast kills one passenger and injures another ten, with a notorious terrorist being behind the bombing.
