Yeah, I kow it did fly. I saw some documentaries even before the movie The Aviator.
My doubt is if it could fly loaded with especified capability (750 passangers).

Empty weight: 113 399 kg (250 000 lb)
Loaded weight: 180 000 kg (397 000 lb)

Yes. But take off loaded with tons of troups and equipment would be even more difficult, am I right ?
I would like to know if Hercules needed all power to take off during the only fly demonstration it ever did.

FWIW: It was supposed to be only a "taxi" but it literally "flew" itself out of the water to everyone's (except Howard) surprise.

I wonder someone today could get all details of the plane, power, aerodynamics for the exact shape, weight distribution, and put on a advanced computer simulation to guess if it could really carry that load (180.000kg).

That depends on how you define efficiency. Figure in the cost of digging a tunnel - abd not just a simple tunnel, but one that will hold a vacuum - to any & every place you might want to go, and the cost of keeping it evacuated, and suddenly it doesn't look all that efficient.

Consider that the cost of building the 31 mile long Channel Tunnel between Britain & France was close to $1 billion per mile (in current dollars).

That's true for basically every airplane, from Piper Cubs to 747s: you use full power for takeoff.

The HK-1 (Hughes-Kaiser) was intended to transport troops & supplies ABOVE the Atlantic ocean, where the German submarines could not attack so easily as they did surface convoy ships. The goal was "above/out" of the water, but not so high altitude as to need oxygen masks for the troops. And, the lower the plane was to the water, the more the curvature of the ocean & earth blocked "line-of-sight" visual tracking from submarines on the surface...called "nap-of-the-earth" flying these days.

NASAs X-57 have so many electric motors for one interesting reason :



They say it will take 1/5 of the power than a usual configuration. Hard to believe.
