I think we should first make the Bob scenario complete.

For this I would like to see made flyable:
Do17
Wellington
CR42
Beaufighter
Sunderland

(I think we can drop the Defiant as people will only try it and drop it as it will be as popular as with the pilots)

I would like to see added as flyable
Armstrong Whitworth Whitley
Handley Page Hampden
109E4 (obviously affirmed to be added soon)
A real Spit 1A with 100 octane fuel and constant speed propeller
A real Spit 2A with a Merlin XII and 100 octane fuel

For the next scenario I'd love to see the Battle of France:
Morane-Saulnier M.S.406
Dewoitine D.520
Fairey Battle (was not really used in Bob as it suffered severe losses during BoF already)
109D
109E1
110D
Ju52
Potez 63.11 (so that the Frenchies can go bombing too )

Here's a list of used aircraft during BoF and the available numbers:

We would need a map that preferably included the Benelux and Northern Germany as the Bomber Command did some raids over Northern Germany (with little success and big losses however as no fighter escort was provided)
