Heartwarming / Executive Decision

• Col. Travis sacrificing himself to make sure the rest are safely on board.
  Grant: Colonel! We're not gonna make it!
  Travis: You are!
  *Travis seals the hatch shut on his side, just before getting blown out into the air*
• Near the end of the movie, when Dr. Grant congratulates Cahill on defusing the bomb.
  Grant: Cahill, I don't know how you did it, but you did it.
  Cahill shakes his head.
  Cahill: No... you did it.
  He then hands Grant the straw from his mouth.
  Grant: What's this?
  Cahill: It's... a memento. Look, I'd love to talk about this, but right now, I need a drink, a BIG drink.
