Looks like a joke to me:
Quote: Cooling: During engine warm up, thermostats cycle engine water through the oil sump heat exchanger to quickly bring engine oil to operating temperature. Once up to temperature, the thermostats then direct engine water to a series of aluminum tubes within the wing. These tubes are immersed in 50 gallons of water which carry engine heat to the wing surfaces which are cooled by the slipstream........
Fuel: A 100 gallon fuel cell below the wing supplies fuel to engine-driven pumps which feed the injectors.
Unquote:
So that's about 400 lbs of Water and 600 lbs of fuel. Not to mentions 2 engines with wacked out props....and looking at the wing area I think it would have to hit about 200 mph just to lift off.
Oh..and I left off this:
Wing: The RP-4 wing is one of the most complex ever constructed. Less than 3 inches at its thickest point, it nevertheless contains flaps and ailerons as well as 200 feet of tubing and nearly 400 fabricated fittings and connectors which comprise the cooling systems.
