Jepsen, Princeton professor of paleontology, who was deep in some digging of his own at Polecat Bench a few miles away. The professor was delighted: old bones associated with arrowheads...
...Advisory Committee for Aeronautics) proved years ago by wind-tunnel tests that the long, graceful wings of bombers are much less efficient above Mach 1 than clumsy-looking "stub" wings. As planes get faster, their wings will probably grow stubbier still until they diminish into something looking like an arrowhead...
...some speeds, thinks the NACA, the most efficient airplane may be shaped like an arrowhead. For others, it may have short, broad "stub" wings. They do not stop at "moderate" speeds such as Mach 1.5, but think boldly about speeds two or three times as fast. Obstacles do not discourage them. At Mach 4, they calculate, air friction will heat the leading edge (perhaps the whole body) of an airplane to about 1,200° F. This is red hot, and above the softening point of ordinary structural metals. "But," say the NACA men, "wings can be cooled artificially...
