Simon (Jeremy Irons) is Hans Gruber's brother (the leader of the terrorists in the first Die Hard movie). The bomb in the school was just to distract the NYPD while he robbed the central bank of all its gold. Bruce Willis and Samuel L. Jackson board the ship. Simon ties 'em up near a bomb. They escape and the ship goes kaboom. Willis, Jackson and the police catch Simon & friends at the Canadian border. Willis forces Gruber's helicopter into a a power line, killing him. "Yippie-kay-yay, motherf%#&er!"
