 FACT: SPOILER: The final scene when Bishop learns that the rescue  operation is called "Dinner Out" is emotionally appealing, but not  believable. Bishop is supposed to hear the voice of the helicopter  pilot when the pilot is talking through the radio of his helmet to  the base "We are inbound, operation Dinner Out accomplished". Bishop  has no helmet, and the helicopter is flying with the rear doors  open. There is no way he could have hear the pilot, who was not  facing him, so he could not even read his lips. The noise of the  helicopter would prevent him from hearing the pilot who was talking  to his microphone in a normal voice.
