Caspian Sea Monster

I was wondering what happened to Huge Heffner's flying monster, looks like it found a home in Russia....

I'm guessing they are way less fuel efficient than a plane. Air density at sea level is much higher than at 20,000', which means much more drag to overcome.

Pretty cool piece of equipment, though.

Might that also mean more richly-oxygenated combustion? Just a guess, no idea if that would weigh into anything here.
