REASON FOR LOSS:

PD117 with a bomb load of 1 x 12,000 lb. 'Tallboy' (1) took off at 07:45 hrs. In common with several other aircraft on this operation, and other operations were flown by 617 around this time, the aircraft flew without a wireless operator and with only the rear air gunner. The Lancaster BI (Special) had a faired off nose turret and the Mid-Upper turret removed and faired over.

20 Lancasters were detailed with an escort of 20 RAF Mustangs. In addition, an attack on an Oil Refinery at near by Bremen would comprise 133 Lancasters of No. 5 Group and 6 Mosquitos from No. 8 (Pathfinder Force) Group, escorted by additional Mustangs.

The Arnsberg Viaduct target was a 200yds long double track Rail link across the River Weser, southeast of Bremen, approached by an embankment and a long low-level steel viaduct crossing the river flood plain until reaching the main bridge comprising three steel girder spans supported on piers.

On this occasion, flak in the target area was more intense than previously encountered for other Bridge targets and a number of aircraft were damaged.

This may have been partly due to the target's proximity to Bremen and also that it had been alerted by the Main Force attack on the port. A number of Me 262 jet fighters were also encountered after the bombing, though they do not appear to have inflicted any damage on the Squadron's aircraft.

Above L-R: Plt Off. Sydney Grimes (not on this trip), Fg Off. Kenneth Gill, Fl/Lt. Joseph Randon, WO. Jack Penswic (not on this trip), Fg Off. Edwin Barnett and Flt Lt. Bernard Gumbley.

A number of Tallboys fell on the south end of the target, with 3 near misses in the river 2 further Tallboys destroyed two piers and brought down 2 spans of the approach bridge to the main structure and a third span was thrown off its piers, with a further one being thrown out of line. Although the main bridge was still intact the target had been rendered unusable.

PD117 was hit by Flak during its run-up to the target, it would have been making its bombing run within the squadron's bombing band of between 12,900ft and 14,200ft. It was hit by flak and dropped out of formation causing Fl/Lt. Gordon Richard Price DFM RCAF flying Lancaster PD118 YZ-M to take avoiding action as the aircraft went past him. British records state that the aircraft received a direct hit and dived down out of control.

Witnesses on the ground gave a different account 'the aircraft went down passing over the village of Okel heading in the direction of Riede at a height of approx 2,000ft'. They do not mention that the aircraft was on fire at this stage, but state that it seemed to be flying extremely slowly. As it flew over Riede the local flak battery went into action, hitting one of the engines and setting the fuselage on fire.

The aircraft made a 180º turn back towards Okel and crashed into a field belonging to a farmer Herr Lippmann. Witnesses said the aircraft did not explode immediately, but before anyone could reach the aircraft a violent explosion occurred 10 minutes after impact, reducing the aircraft to fragments and creating a crater 50ft deep by 100ft in diameter.

The RAF Missing Research and Enquiry Service failed to find any German documentation regarding the incident or trace any burial for the crew. The identity of Flt Lt. Joseph Randon was established from a document found at the crash site, leaving no doubt about the identity of the aircraft. No evidence was found that the crew had been found and a search of the cemeteries for crew members was also unsuccessful. It was assumed that the crew had still been aboard the aircraft when it came down and perished in the crash and explosion, the water-filled crater 20 metres deep and 30 metres across prevented any further investigation or recovery.

(1) Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force during the Second World War.

At 5 long tons, it could be carried only by a modified model of the Avro Lancaster heavy bomber. It proved to be effective against large, fortified structures against which conventional bombing had proved ineffective.

Tallboys were largely hand-made, requiring much labour during each manufacturing stage. The materials used were costly, with precise engineering requirements in casting and machining. To increase penetrative power, a large, specially hardened, steel plug had to be precisely machined and mated to a recess in the nose of the bomb. The ogive had to be perfectly symmetrical to ensure optimum aerodynamic performance. This was no easy task when manipulating a bomb casing with the size and weight of a Tallboy.

The Torpex filling was poured by hand into the base of the upturned casing after melting it in 'kettles'. The final stage of explosive filling required that a one-inch layer of pure TNT be poured over the Torpex filling, followed by sealing the base with a 4 inch layer of woodmeal-wax composite with three cylindrical recesses fitted with the explosive boosters and into which three chemical time-fuses were inserted when the bomb was armed.

Tallboys were not considered expendable, and if not used on a raid were to be brought back to base rather than safely jettisoned into the sea. The value of the weapon offset the additional risk to the aircrew. Given their high unit cost, Tallboys were used exclusively against high-value strategic targets that could not be destroyed by other means. When it was found that the Lancaster could be modified to carry a bomb larger than the Tallboy, Wallis produced the even larger 'Grand Slam' bomb. Information courtesy Wikipedia)
