I always thought that French planes of the 20s and 30s had all the weirdness and uglyness records (I love all of them though, I'm afraid I have some odd taste for strange planes
)
But since Gerax has taken most of them, I think that this other one deserves a place of honour:
The British Tarrant Tabor.
The awful R-1 at least flew a couple of test flights (crashing in both), but this British monster crashed in its maiden flight in front of a lot of public because they loaded its nose with extra weight thinking that would make it more stable.
In that moment was the biggest bomber ever constructed, but arrived in 1919, too late for WWI. Anyway, I was thinking to request this and other of these monsters that deserve the chance to fly even virtually. I'd love if someone made a mod of this and we could try to finally take off with it...or shoot it down.
