The main gear doors were unnecessary; the horizontal tail belonged at the top of the verticals, but the 336/337 always was a fine civil OV-10 alternative. But it was the airport noise champ until the Starship came along. One oversize clamshell airstair door would have been sufficient.
With centerline thrust, it was way ahead of its time. And one of the most beautiful planes that Cessna ever built.
As a sort-of-electric airplane, they could do a lot worse than the Skymaster. I wish them well.
