A force of 257 bombers comprising 101 Wellingtons, 74 Lancaster, 59 Halifaxes and 23 Stirlings was despatched on this raid to bomb Aachen. Icing and severe electrical storms played havoc with navigation over the UK and continued to be bad over Germany. Lack of accurate Pathfinder marking over the target resulted in most of the aircraft failing to bomb Aachen, their bombs falling on other areas. Reports from Aachen estimated little more than 10 aircraft actually carried out the raid with their bombs falling mainly in the southern suburb of Burtscheid killing 5 people and injuring 39.

The majority of Pathfinder marking seems to have been made over the Dutch town Lutterade some 17 miles north west of Aachen where more than 800 houses were seriously damaged, 83 people killed, 22 injured and 3000 rendered homeless.

A total of 10 aircraft were lost and a further 6 crashed in England possibly in thunderstorms.


Posted to No. 22 OTU at RAF Wellesbourne Mountford on 26 May 1942 Mike O'Driscoll, Sandy Sandiford, Johnnie Armstrong, Cliff Challis and Johnnie Howells were thrown together in the time honoured ritual that was crewing up.

Sandy and Johnnie Howells however were already well acquainted, having attended public and high school together in Toronto and had also enlisted within several weeks of each other. Sandy and Johnnie were both engaged to Toronto girls Louise Caddel and Elsie Wegg respectively and the two couples were to be married in a double ceremony as soon as the airmen returned home from overseas.

Whilst at 22 OTU the crew are known to have taken part in the 630 bomber raid on Dusseldorf on the night of 31 July/1 August 1942 flying in Wellington 'P bar.1588'.

On 22nd June 1942, an organisation order was issued authorising the formation of a fifth RCAF bomber squadron overseas. The order carried unprecedented significance in that its heading included after the squadron number the words 'French-Canadian'. This made the unit unique in RCAF history. Designated No. 425, it actually came into existence three days later (25 June 1942) at Dishforth, Yorkshire, as a unit of No. 4 Group.

Flying commenced in August and on the 14th the crew was posted to the Squadron which was declared "Operational" in early October, the original aircrew strength being twenty 5-man crews.

On the night of 5/6 October 1942 425 Squadron was given its operational baptism when eight of its Wellingtons were detailed to take part in the bombing raid on Aachen, Mike O'Driscoll and his crew were one of the eight.

The eight Wellingtons of 425 Squadron took off from RAF Dishforth at roughly 18.30 on 5 October.

Heavy thunderstorms all over the UK were claiming victims even as the bomber force set out. No. 156 Squadron was so badly affected that of the twelve aircraft detailed for the raid only five managed to get airborne.

The violent electrical storm and its habitual accompaniment, icing was a continuous threat and two aircraft of 425 Squadron were forced to turn back with severe icing.

Little is known regarding the fate of Wellington X3943 and its crew except that having taken off at 18.47 it crashed at 19.55 hours less than 200 miles from Dishforth at Boyton Hall Farm, Finchingfield, 8 miles northeast of Braintree, Essex. However it would seem likely that the cause of the crash was directly linked to the thunderstorm and/or its attendant severe icing. Some RAF records state that the aircraft was returning from the operation, in view of the time of the crash this would seem to indicate that the aircraft had turned back probably due to icing.

All five crew perished in the crash, the cause of death of each of them was recorded as due to multiple injuries and burns. The five bodies were taken to the mortuary at RAF Debden near Saffron Weldon, North Essex. The five were laid to rest side by side on Friday 9 October at Saffron Weldon Cemetery with the two pals from Toronto, Sandy Sandiford and Johnnie Howells lying adjacent to each other.


On 11 June 2019 Aircrew Remembered was contacted by Lindsey Weightman. Lindsey shared with us the following story as related to her by her mother, Mrs Honor Wilson Weightman nee Hartley now in her 96th year.

Honor was due to meet Mike O'Driscoll to go dancing in Ripon near RAF Dishforth where he was based. Whilst waiting for him under the clock just outside the Lawrence Ballroom she was approached by an airman who asked

"You waiting for Mike?"

"Yes" she answered

"Well he's had it." said the airman (his exact words)

But though Honor always considered herself to be a very caring person she admits that her first thought was, "Oh! How will I get into the dance without a ticket?" Yet that was her initial reaction.

Looking back she can only think that those of her generation were just products of an era that had grown so accustomed to death that they did not find it shocking.

The memory of the event has stayed with Honor all these years.
