Bond oil rig
Whyte identifies an oil platform off the coast of Baja California as Blofeld's likely base of operations. After Bond's attempt to change the cassette containing the satellite control codes fails due to a mistake by Tiffany, a helicopter attack on the oil rig is launched by Leiter and the CIA. Originally the oil rig finale also had Blofeld escape from the rig in his mini submarine, pursued by Bond who would hang from a weather balloon. Bond would eventually catch up to his nemesis in a salt mine where the two would finally fight to the death, with Blofeld falling into a rock crusher.
