Apologies for my limited aerodynamics (remembered from the Air Cadets years ago) but surely flying nose down will result in a lower angle of attack (alpha) and therefore less drag.
It will of course result in less lift which could be recoved with more power.

I thought it looked more like an Argosy

I’d be interested to know if anyone has any information to flesh out my limited amount on two British parachuted weapon systems.
The first was one that was dropped, if only during testing. The Boom Patrol Boat, this was an explosive filled speed boat (copied from an Italian design) for the early Special Boat Squadron that was dropped from a Lancaster B1 special with its crew aboard, a Lt Cox was the first but I understand that Blondie Haslar also had a go. I only have the description of the Lt Cox’s drop in a book along with the grainy photgraphs it contained
The other proposal only got as far as building its parachute, was the airdrop of the Welman one man midget submarine, again with its crew already on board. The parachute for this project was so large that it had to be packed in the road outside the GQ parachutes works in Woking and when packed weighed in at 1000 lb !
This idea must have been from the same deranged mind that had the idea of hanging two Chariot submersibles from a Sunderland.

The Museum at Middle Wallop had the rear fuselage of a Hotspur glider and on the principle of “its a small one nad wouldn’t it be nice to have a complete aircarft” , the museum’s Horsa’s Hadrian and Hamilcar being far from complete due to space consideations, the rest of the airframe was built. On completrion the museum higherarchy was heard to say “I thought you said it was going to be small”.

If no genuine aircraft exist a (good) replica has a place in a museum if only to give an idea of the size. Go to RAF Shawbury and stand in awe in the shadow of the Horsa replica there to get a true idea of this Medium glider’s size. Role on a complete Hamilcar restoration/ replica.

its XS596 the Open Skies aircraft.
Its currently sat outside my office window with XS646 sat alongside.
