The working of Rebecca-Eureka radar device for dropping bombs over blind targets.
A training film 'Blind Bombing' depicts Rebecca-Eureka radar device being used for low level bombing over blind targets. A bomber aircraft in flight at a low altitude over the forest. The OSS (Office of Strategic Services) officers look at the plane. Animation depicts the Eureka agent guides the Bomber aircraft in flight. The OSS men carry at the field. A hand of OSS ground agent encircles the enemy objective in his area. Bomber aircraft in flight over the objective area. A parachutist jumps in the target area. Animation shows the ground agent helping the Eureka agent to enter the target area. A part being selected for setting up Eureka beacon. A man hold Eureka, a radar beacon in his hand. U.S. Army Air Forces A-20G Havoc fighter aircraft in flight. The Rebecca operator in a cockpit. The Rebecca operator reads an indication. The aircraft in flight from where the beacon can give signal. OSS officers looks at the enemy location on a map. A parachutist boards the aircraft. The aircraft in flight. The ground agents look at the enemy target. The parachutist jumps at the target area. The agents runs and help him to gear off and they leave the field. They look into a paper. Both of them read the bombing table and set the Eureka location according to it. The Eureka being set up and tested. The ground agent activate the Eureka. The pilot and Rebecca operator get in the aircraft . Pilot at controls. The aircraft in flight. The beacon contact being made. The operator looks from the siliscope and signals back to Eureka. The aircraft in flight over the beacon. Animation describes the Seliscope pattern and aircarft in flight according to the beacon position. Aircraft in flight and Rebecca operator sends the alert signal. The ground member in contact with the Rebecca. The operator picks up the bomb release and in action. The ground agent gives signal and the bomb being drooped. Animation depicts the bomb being dropped at the right position (World War II period).
