I don’t disagree, although I’d want to move the engine up like on a P-38 to increase ground clearance for more use on marginal runways.
I could really see a really, really simple plane like this being very useful as cheap ground support, like less than $1million a plane.
Keep in mind that the recovery and restoration to flight of the P-38 Glacier Girl cost about $10 million, at the time. And the guy who led the restoration (Bob Cardin) said that every part on the aircraft was broken and had to be fixed or replaced.
