The crew’s kit and personal belongings were removed from their lockers and catalogued; kit was returned to stores and personal belongings sent to the RAF Central Depository at RAF Colnbrook.

The Air Ministry Casualty Branch, which was responsible for investigating, monitoring and reporting on the status of missing aircraft and airmen, subsequently published the following information regarding the crew:

  • Air Ministry Communique No. 79 (Flight 18/09/1941) reported RV Collinge and DJ Mennie as “missing, believed killed in action”. Also RA Bates, ERPS Cooper, JMR Cruickshank, AJ Heller and E Short as “missing”

  • Air Ministry Communique No. 126 (Flight 23/04/1942) reported RA Bates, ERPS Cooper, JMR Cruickshank, AJ Heller and E Short “previously reported missing” as “now presumed killed in action”

Note: Presumption of death enabled a death certificate to be issued; personal belongings could then be returned to the next of kin, along with any monies due

No. 35 Squadron’s Operations Record Book shows the following information was received relating to the crew:

  • 16/08/1941: Information received, passed on from International Red Cross Society, that F/S Collinge and Sgt Mennie of PO Cooper’s crew, missing on operations 25th/26th July 1941, were killed

Post War search for the missing crew members

After the war, an investigation officer from the Royal Air Force Missing Research and Enquiry Service (MRES) was tasked with locating the remains of the missing crew member(s).

Original German documents, burial records and eye witness accounts were utilised to establish the location of the crash site, the cause of the loss and the initial fate of the crew; information was recorded in a MRES Investigation Report.

German Record for RV Collinge

As part of the process, any remains that were located were exhumed, identified (wherever possible) and concentrated (reinterred) at one of the Commonwealth War Graves Commission’s (CWGC) Cemeteries in the country that they fell, in accordance with Government policy at the time.

Graves were marked with a simple wooden cross, which was replaced by the familiar CWGC headstone during the 1950’s.

Missing airmen who could not be found, or formally identified, had their names commemorated on the Air Forces Memorial at Runnymede, which was unveiled in 1953.

CWGC records show that the remains of all members of the crew were located at Doberitz Standortfriedhof
