...actual speed and range were not released, partly because they are legitimate military secrets, partly because the airplane has flown so far only in wind tunnels, and its true performance can only be estimated. But the Government claims it will be faster (about Mach 2.5, or 1,650 m.p.h.) than any operational plane. It will fly twice the distance and carry twice the payload of the best current U.S. fighter. By cruising at moderate speed with wings extended, it will have "transoceanic range without refueling"; if permitted to refuel, it can fly to any part of the earth...

...power, the F-111 uses two radical TF-30 engines built by Pratt & Whitney Aircraft. At slow cruising speeds, they are turbofans similar to the engines on up-to-date jetliners, very sparing of fuel. At Mach 1 and above, the fan action is cut down or eliminated. When full power is called for, the engine uses an afterburner. Aerodynamicists credit the versatile engines as well as the wings for the varied talents...

...there will be many other cautious flights before the B70 starts its lifework: exploring the swarming problems of a Mach 3 airliner. And if such a passenger plane ever goes into service, much of the credit will go to the technological innovations that were first tested by Cecil the Seasick Sea Serpent...

Splendid Parade. Far from a slight extension of Einstein's work, Hoyle's apple stealing is more ambitious larceny. His new theory stems from the Mach Principle, that the mass* of every object in the universe is affected by its interaction with every other object. Einstein tried to incorporate the Mach principle in his own scheme of the universe and admittedly failed. Hoyle claims to have succeeded...

...Mass is that property of a body which resists change of motion. On the surface of the earth, it is closely equivalent to weight. Austrian Physicist Ernst Mach (1838-1916), who gave his name to the principle, is better known today for Mach numbers, a method of measuring speed in multiples of the speed of sound...
