Abstract
YALDEN, in calculating the flying speed of Archaeopteryx, states1 that he includes the areas of the body strip and tail, and assumes the same lift coefficient for both the wing and tail surfaces. Heptonstall in an earlier letter2 does not include the body strip because “it does not behave like an aerofoil in generating high lift”.
