NOVA — S43E22 — Bombing Hitler's Supergun

00:00:03 NARRATOR: It is the height of World War II

00:02:40 This enormous cannon would be buried deep underground

00:04:47 NARRATOR: How did it work?

00:07:06 Hitler was determined to strike back

00:29:21 You might be jumping out

00:31:23 SPARK: The TV camera made the drone

00:33:07 a bomb that would explode underground

00:35:44 but in fact, that's only part of the damage

00:40:11 so the hill remained a prime target

00:42:11 and I looked in every nook and cranny there is:

00:44:20 to send a pulse of electricity to the solenoids

00:47:19 NARRATOR: No one will ever know for sure,

00:50:14 and for the infrastructure for the gun

00:52:11 has ever successfully deployed a supergun
