The F-8A Supercritical Wing (SCW) aircraft in flight. Dr. Richard T. Whitcomb began work on the supercritical wing in the early 1960s. Although the design was highly efficient in wind-tunnel testing, it was so unusual that few accepted the concept as practical. Larry Loftin of NASA's Langley Research Center in Hampton, VA, said, ''We're going to have a flight demonstration. This thing is so different from anything that we've ever done before that nobody's going to touch it with a ten foot pole without somebody going out and flying it.'' The Navy supplied NASA with an F-8A (Navy Bureau Number 141353/NASA tail number 810), while North American Aviation built the supercritical wing. The SCW team attached it to the stock F-8 fuselage. This 1971 photo shows its original paint finish. Tom McMurtry, who was the lead project pilot, recalled that there was no time or money for a fancier finish. In fact, on the first flight, made on March 9, 1971, the ''SCW'' on the tail was actually taped on.
