...popping, and the gas belches out of your throat. At 40,000 feet you feel small and high. Mountains are wrinkles in green-and-brown cloth, and cities are patches of ragged wire screen. The upper altitudes are silent except for the slight singing hum of the whirling rotor behind...
...Forty-one manestically spaced grouting brushes were arranged to feed into the rotor slipstream a mixture of high S-value phenylhydrobenzamine and 5% reminative tetryliodohexamine. Both of these liquids have specific pericosities given by P = 2.5C.n^6-7 where n is the diathetical evolute of retrograde temperature phase disposition and C is Cholmondeley's annular grillage coefficient. Initially, n was measured with the aid of a metapolar refractive pilfrometer . . . but up to the present date nothing has been found to equal the transcendental hopper dadoscope...
Almost any G.I. in China theater could have enlarged the indictment. Widespread thievery is the secret grievance the average American soldier holds against China. At one base the rotor and timing gear on a tractor used for loading heavy bombers were stolen. The parts could not be replaced in China...
...standard Sikorsky helicopter has a rotor on top, for lifting, and another in the tail, for steering and to counteract the twisting effect given the ship by the top rotor. Hiller decided that the tail rotor was all wrong: it added unnecessary weight, wasted power, set up turbulence around the ship. His solution: two rotors on top, mounted on the same shaft but rotating in opposite directions...
Using a new mechanism, a military secret, which controls the pitch and speed of the two rotors (either or both), Killer's "Hillercopter" is driven and steered by the top rotors alone. Advantages claimed by Hiller: his machine is much easier to pilot, can be parked in a garage by folding the rotor blades, will eventually fly farther and faster, because of its lighter construction, than other helicopters. He said he had already flown his 90-h.p. model at 100 m.p.h...
