...composer who can lure Manhattan critics into taking a 30-minute train ride to the suburbs to hear a piece of music must have something on the ball. Blade-thin, Manhattan-born Norman Dello Joio apparently is one composer who has. When New York's progressive Sarah Lawrence College put on his first opera last week, Manhattan critics and admirers traveled right out to Bronxville to hear...
Wasp Waists. Searching for a prop that could be used efficiently above 450 m.p.h., Hamilton's engineers, led by Chief Aero-dynamicist George Rosen, tried all sorts of shapes. One design, intended to sidestep shock waves, had curved blades, quite like the swept-back wings of a fast modern fighter. Another had a blade with a pinched-in "waist." Some blades were short and broad so that they could spin rapidly without nearing sonic speed. All these designs proved unsatisfactory...
Hamilton's prop men designed a thin, knife-edged blade of conventional, square-tipped shape that would move fast enough all along its length to leave shock waves behind. This did the trick. Tested in a wind tunnel, a scale model of the new propeller proved to be 80% efficient at 600 m.p.h. No shock waves roiled the air-flow over its smooth surfaces. Shock waves are not quick enough...
...Uline Arena, Button put on a remarkable exhibition of his own improvised "free" skating. He executed three consecutive spinning loops in the air in one figure, and a flying leap in another. In this jump he does the splits six feet off the ice, touching his outstretched skate-blade ends with his hands...
...Future. The garden variety of double-Axel, which was the Button sensation of 1949 in the free-skating event, requires the performer to come into the jump skating backwards. The rest of the requirements: a tremendous leap, 2½ body spins, a feather landing, and a smooth blade-cut left in the ice. Few skaters can think of attempting it; this year Button did two in a row, to make it a double-double without the slightest pause, covering 30 ft. in the whole involved maneuver in about two seconds. He was glad when the double-double was over. "Those...
