REASON FOR LOSS:
On the night of the 23rd/24th October 1944 625 Squadron were detailed to join a force of 1055 bombers on an operation to bomb Essen.
PA174 return was routed to cross the English coast at Orfordness, above 10,000 feet just north of Clacton-on-Sea. The aircraft was seen to dive out of cloud about 4 miles north of Clacton-on-Sea. It was seen to describe a left hand orbit and dived into the ground near Weeley Lodge in Essex at 21:08 hrs where it exploded and burst into flames. The aircraft appeared to be diving under full power.

At the time of the accident the cloud base was approximately 1,800 feet and cloud extended to some 22,000 feet with severe icing conditions in cloud. From photographs of the wreckage it appears that the aircraft dived steeply into the ground. It is not possible to state whether this was due to icing or loss of control when flying on instruments. Parts of the outer nacelle fairings and maps were found on line of flight of aircraft over 2 miles away from scene of the crash.
No evidence could be produced to provide a definite cause of the accident but the Court of Inquiry concluded that a combination of the two probable causes were contributory factors in the crash:
The air speed indicator and static vent may have iced up, and the pilot may have opened up the throttles and. pushed the nose down to prevent stalling, thus going into a high speed dive.
The pilot may have failed in his instrument flying during the descent through 13,000 feet of cloud and he may thus have lost control. This theory is supported by the orbit made before the crash occurred.
Note: This was a new aircraft with just 6 hrs and 50 minutes on the airframe and Plt Off. Tweter was on first operation as Captain.
PA174 was one of three (3) aircraft from the Squadron that failed to return. The other two were:
Lancaster III LM691 CF:O - Flown by Sqn Ldr. Charles W.C. Hamilton which was involved in a mid-air collision with 462 Sqn Halifax III LL599 whilst returning from the operation. Sqn Ldr. Hamilton survived whilst his crew perished;
Lancaster III PB531 CF:H - Flown by Fg Off. Owen Henry Morshead. The aircraft and crew were lost without trace.
(1) Fg Off. Collingwood had two brothers and a sister who also served. WO. Bernard Thomas Collingwood RCAF and Sub-Lt Francis Joseph Collingwood RCN at Halifax. WRNS Rita Mary Collingwood. All survived the war.
(2) Sgt. McKendry had one brother who also served. Thomas Edward McKendry was serving at No 5. OTU RCAF at Abbortsford in British Columbia, Canada. He Survived the war.
(3) Sgt. Smith had two brothers who also served. Sgt. Achilles W.W. Smith M63204 who served with the 1st Canadian Armoured Brigade, 83 Company RCASC, overseas. Yeoman of Signals V12252 Robert B. Smith who served in HMCS Chatham, Prince Rupert, British Columbia. Both survived the war.
His eldest brother, Leading Signalman Cedric De Herries Smith 2533 RCN serving in HMCS Margaree and was posted MiA on the 22nd October 1940. HMCS Margaree was sliced in two in a collision with a convoy Merchant freighter, Port Fairy. He was amongst the 142 souls to go down with the forward part of the ship. He is remembered on the Halifax memorial Panel 4.
