Here is a double-sided worksheet of questions that go with the PBS NOVA video Bombing Hitler's Supergun. The questions come in the order the content appears in the video so that students can fill out the answers while they watch.
The video tells the story of the British and American plans to destroy a supergun that Hitler's military had invented. It demonstrates the engineering principles involved in the gun and the two different attempts to destroy it. One attempt by the British used a newly created bomb that would explode underground. The other involved a drone aircraft bomber that would crash into the gun's bunker. The drone was piloted by Joe Kennedy, John F. Kennedy's older brother who was supposed to go on to run for president. The mission killed Joe Kennedy. The show explains why the plane exploded too early and how a soldier figured out the danger and tried to warn them before the mission happened.
