@Lustig Andrei,
I caught it on TCM several months back. There is a scene with George C. Scott in a command center playing a General (I think?) who try's to explain the range of the bombers accidentally on their way to Russia. He's asked how long they can travel once the fuel runs out and gets so caught up in describing how marvelous the design is and what could be done once the tank is empty, he forgets what they are about to do and suddenly snaps up straight with his hand clapped to his mouth when the enormity of the situation snaps him back to reality.
