Three Liberties
Description from aerofiles.com sums it up nicely...
Multiplane 1919 = Odd visual effect with what appeared to be one-and-a-half biplane fuselages and wings joined in tandem, with a triplane inserted in the middle, all of this propelled by one Liberty motor in the nose and two more as interwing pushers. Herbert Johns. Needless to say, it was huge. After several hopping tests, the septi-wing just barely cleared the ground on its test flight before nosing up and settling ungracefully. When more attempts in 1920 proved conclusively that the machine was not particularly interested in flying, it was scrapped.
