I have found some information about two of these airman, I am hopeful that someone can come up with more.
I believe the airman back row, third from left is Israel Jacobovitch who served under the name of Jackson.
He was lost 9 days after joining 50 Squadron in Hampden AE 226.
Bousfield second row, third from right.
On 19th July 1941 50 Squadron moved from Lindholme to Swinderby. The squadron departed Lindholme in formation. Shortly after takeoff the airmen were horrified to see Hampden AD 897 roll onto it’s back and fly inverted for a few seconds before diving into the ground killing Sgt. Bousfield and crew.
