We are hopeful that Rolls Royce can provide us with details of date of manufacturing and/or date of delivery to the production factory.
If they have archives listing possible airframe/aircraft or construction numbers then we would be very lucky indeed.
If we can link the delivery date to the production factory then we might be able to list the batch of engines under the contract number to possible aircraft numbers produced from around that date.
From there we could check if any aircraft from this batch are listed as missing/crashed in the area of our crash site in Normandy.
The search continues…
