RAF Non-operational loss 21 March 1944

[Icare9]

It's been reported on the Halifax forum as being a Ferry flight by 301 F.T.U / O.A.D.U to the Med. On 22nd March JP107 took off on a similar flight, landing at Celone near Foggia and 614 Sqdn, so JP137 could have been doing the same.

Most RAF crew were buried near their homes. McGregor being RCAF was buried at Brookwood Military cemetery. There are a number of other RAAF etc casualties, none allocated a Squadron, that may have been aboard, but all previous evidence has only come up with a 5 man crew. Was that usual for long distance ferry flights?
