Flight of the Phoenix

Frank Towns: Look, how can I let those people build that plane when I don’t believe it will work? And, every day they waste trying to build it brings them one day closer to dying.
Liddle: I think a man only needs one thing in life. He just needs someone to love. If you can’t give him that, then give him something to hope for. And if you can’t give him that, just give him something to do.
Frank Towns: James, you’ll never make it.
Liddle: Then I’ll die trying. There are people counting on me.
Frank Towns: Okay, Okay, Okay. Okay. We’ll build it.
