Bruce McCall has some illustrations of interesting planes:
Humbley-Pudge Gallipoli Heavish Bomber
Septum NC 2501.2 High-Altitude Bomber
And let us not forget The Snud U-14 Military Transport.
The B-58 Hustler.
Definitely an answer waiting for a question.
It was:

[li]Developed to avoid Soviet SAMs which ironically could shoot it down anyway[/li][li]Then changed to a low altitude bombing role for it was completely ill-suited[/li][li]Frequently in need of repair (a hangar queen)[/li][li]Only in operation for ten years before being quietly replaced by the FB-111A[/li][li]Never even used in a conventional bombing role[/li][/ol]
Saw a number of them at DM in Tucson in the late 1980s.
Great looking plane for an expensive boondoggle.
That it was. A really beautiful aircraft. And it could fly fast and far, no doubt about it.
Some of the *Between the wars but actually used for a few months during WWII *French “flying greenhouse” bombers come to mind such as the Amiot 143. Slow, underarmed, not long range, and with a poor payload.
The Breda BA.88 looked cool. It’s opposite was the Polish Zubr, likely the ugliest airplane to fly.
The winner has to be the MXY-7 Ohka (Cherry Blossom).
