Still from film shot by the RAF Film Production Unit during Operation HURRICANE. Avro Lancaster B Mark I, NG128 'SR-B', of No. 101 Squadron RAF, piloted by Warrant Officer R B Tibbs, releases a 4,000-lb HC bomb ('cookie') and 30-lb incendiary bombs over the target during a special daylight raid on Duisburg. Over 2,000 sorties were dispatched to the city during 14-15 October 1944, in order to to demonstrate Bomber Command's overwhelming superiority in German skies. Note the large aerials on top of the Lancaster's fuselage, indicating that the aircraft is carrying 'Airborne Cigar' (ABC), a jamming device which disrupted enemy radio telephone channels.
