[Six Nifty .50s]

That sounds like the end of Blenheim V5568 of the 1401 weather flight, last seen on 27th May 1942. Reputedly shot down in error by an RAF Whirlwind pilot from 137 Squadron. Flying Officer Marshall, Sergeant Thimblebee, and Sergeant Gray were never heard from again and reported MIA.

Found it in Graham Warner's fine study from Crécy Publishing. Unfortunately there were many known losses of Blenheims to own fire; I will list the whole lot when I finish reading it.
