^ THE Fl HILE it is true that the first aircraft to achieve supersonic speed—America's Bell X-i—is of elementary straight-wing configuration, it is now certain that in the immediate future civil and military machines designed to operate in the high-subsonic and transonic regimes will display unorthodox wing forms, as typified here. Both the de Havilland Comet airliner (above) and the Vickers-Armstrongs 660 bomber (right) have moderately swept, heavily-tapered wings of deep root chord. At upper right are the latest (dorsal-finned) version of the Vickers-Supermarine 535 experimental fighter, photographed over the sea, and the Hawker P.1081, both of which have sharply raked wings to permit speeds far in excess of 600 m.p.h. Below, from left to right, are the three British deltas now flying—the Fairey F.D.i, Boulton Paul P.m, and Avro 707B.
