...leopard. "I'm completely exhausted," he confided by phone to Peter Lind Hayes, who is substituting on his morning radio and TV shows. Peter occasionally let viewers hear the familiar adenoidal wheeze: "It looks bloop bleep like Wyoming. It's 123 degrees. You get headaches from the heat. But boy, that Bufferin [a sponsor] has been a godsend. By George, it's wonderful...
...result of chemical reaction. This definition excludes nuclear "fuels." e.g., U-235, but it includes thousands of lesser energy-yielders. Petroleum hydrocarbons (gasoline, kerosene, etc.) are the commonest aviation fuels only because they are plentiful, convenient and relatively cheap. Many other chemicals yield more energy. Hydrogen has the highest heat of combustion (52,000 B.T.U.* per lb.), but carbon is rather low (14.500 B.T.U. per lb.). Hydrocarbons, which contain both carbon and hydrogen, are therefore intermediate. Kerosene burned in jet engines yields only about 18,500 B.T.U...
Fortunately, nature has provided a chemical element, boron, which can be forced with some difficulty to improve on carbon's performance. Boron has a high heat of combustion (25,000 B.T.U. per lb.), and it forms compounds that contain more energy-rich hydrogen than most hydrocarbons do. The heat of combustion of diborane (B2H6), for instance, is 31,000 B.T.U. per lb., almost twice as good as kerosene...

...sure hand on the wheel and leaves the rest to luck. In a race like this week's test at Sebring, so much can go wrong that he feels luck is unusually important. The 5.2-mile course has so many tight turns and wicked switchbacks that brakes heat up and fade, clutches tend to wear out under constant shifting...
