Picture should have been taken after or during the end of World War II, probably close to Marrakech French base (but that is not sure). Can anyone tell us what these planes are? My grand father could be one of the pilots and I would like to find information on him.
It's an RAF Coastal Command Vickers Wellington, a maritime patrol variant, with a chin radome for its search radar and the nose turret removed and just greenhouse for observing. The dark projection on top just above the cowling is a fairing for a Direction Finding loop antenna on the fuselage. The dark shapes farther back are just dark painted areas. Here's a shot of a similar one:
If you're sure the picture was taken near Morocco, it was probably doing sub hunting in the Mediterranean and nearby Atlantic. Likely with 179 Squadron, based at Gibraltar.
