Took off from RAF Kabrit at 20.20 detailed to attack the harbour and shipping at Tobruk, Libya. On the return journey it became evident that they had insufficient fuel left to reach RAF Kabrit and being unable to find LG224 at Cairo West Kilo 26* (Gebel el mansuriya) made for RAF Heliopolis in North East Cairo.

The initial Cypher report to Air Ministry, Kingsway, Melbourne reported that the crash occurred at 04.30 on 12 July and that the aircraft had "Approached aerodrome too high on attempting to land, opened up throttle to circle aerodrome again but aircraft stalled and crashed."

In his book "Bomber Losses in the Middle East and Mediterranean" David Gunby adds that DV674 "collided with [Wellington] AD601 on overshoot".

*Kilo 26 (26km being its distance from Cairo up the road to Alexandria)

Bob Chalmers and Thomas Roberts, the two pilots, were killed in the crash. Ivor Thomas the front gunner sustained serious multiple injuries and was admitted to 9 British General Hospital Cairo. Wireless Operator Harvey Wigley was admitted to the RAF Hospital with cuts and concussion whilst Observer Maurice Richards and Rear Gunner Sergeant Luck although admitted to Station Sick Quarters (SSQ) at Heliopolis with slight injuries were discharged to duty the following day 13 July.

In a statement dated 13 July 1942 the Observer Sergeant Maurice David Richards reported that:

"At about half-way to the target, the pilot said that he had no control on the throttling of the starboard engine. Owing to this defect he was forced to keep the mixture at "rich". Due to this we had very little petrol left when we reached the Nile Delta. We reached the Nile and from there we got 2 QDMs [Magnetic headings] to Heliopolis Aerodrome.

The pilot hardly recognised it as an aerodrome and in my opinion was confused by the lights from the Prisoner of War Camp. After circling approximately 4 or 5 times he was forced to land. Being unable to see anything of the outside from my position this is the last evidence I can give till we hit the ground.

Although this was my first flight with F/Sgt. Chalmers (the Captain) he seemed an excellent pilot throughout the trip."

Sergeant Harvey John Wigley the Wireless Operator added that:

"On landing, our aircraft collided with two other aircraft which were stationary and caught fire." He timed the accident as 04.00 hours and said that he was then admitted to RAF General Hospital (Egypt) suffering from concussion, broken ribs and cuts to both legs and face which were stitched.

On 14 August 1942 the Commanding Officer of 108 Squadron stated that he was "satisfied that the holding of a Court of Inquiry or Investigation would add nothing to the report."
