Description

2 B-17s from 482BG are despatched to the German city of Duren to perform a test of the OBOE navigation system. Oboe was a British aerial blind bombing targeting system in World War II, based on radio transponder technology.[1] Using triangulation to determine relative location, the system consisted of a pair of radio transmitters on the ground, which sent signals which were received and retransmitted by a transponder in the aircraftt (typically a De Havilland Mosquito or Avro Lancaster). By comparing the time each signal took to reach the aircraft, its location could be calculated to a fair degree. In this way, an aircraft could be directed blindly over a specific target, all of which were pre-calculated and kept on file. ref. https://en.wikipedia.org/wiki/Oboe_%28navigation%29. 1 Aircraft turned back due to equipment failure and the other dropped on ETA due to special equipment failure.
