While the military Lockheed P-38 Lightning is famous, the civilian L-1038 Constellightning failed to seduce airlines, despite its similar beauty:
If Lockheed absorbed Budd aircraft to get their stainless-steel fabrication expertise, then built a cargo version of this design with a high wing and a tail ramp (think AW Argosy), they could call it the Constellightoga......
... but would it still be "obviously civilian"?
Sure, the A-W Argosy originated as a civil freighter aircraft that was later adopted by the RAF,so a Constellightoga could have a similar history.
So... here is my first try of a LBW (Lockheed-Budd-Weaver Inc.) Constellightoga:Thanks again!
Back in 1935, the Lightning-design source was also civilian (and was a flying boat): Lockheed Twin-Hull Liner
Lockheed marketing department had scheduled the sell of 100,000 improved TFL-2 but this failed alas:
Thanks ericr...Well, while the Twin-Hull Liner was not ordered at all, its derivative the Twin-Fuselage Liner reached 38,038 orders (38,380 copies built, including spare parts). I swear this is true (in my dreams at least):
