A 1/350 Ark Royal, I'd buy that.
Airfix can good begin to re tool their RAF sets; refuel, recovery, rescue. Just as long as they up scale them to 1/48 as well. That is 1/72 and 1/48, don't want to upset any one do we.
Also in 1/48 it would be nice with some period correct civilian vehicles from WWII.
And here is the curve ball: How about sections of aircraft carriers. A lift, some of the super structures, be great for diorama/bases.
