Chugalug (your #7876),
... There may be some quibble about the use of Lockheed Hudsons on night close formation raids...
Three "Bettys" set out in formation with their nav lights on to bomb Calcutta. Unfortunately the pretty display drew the attention of a F/Sgt Pring, who was on patrol with a Beaufighter.
He crept up behind and blew all three out of the air, for which he got a DFM. Was shot down later himself and killed in Burma.
It's just the way it is. Danny.
