From his game-bag protruded the curving claws and wing-tips of a great bird.
The hawk followed, his wing-tips now almost brushing the water.
It is sometimes advanced that it is owing to the "spill" of air from under the wing-tips.
Muzzles of compressed air guns projected from the wing-tips of the planes.
The main surface towards the wing-tips is given a decreasing angle of incidence and corresponding camber.
In order to secure the longitudinal dihedral, the angle of incidence has to be very much decreased towards the wing-tips.
The board is cut to the same angle as that specified for the upward inclination of the surface towards its wing-tips.
A slight movement of the tail-feathers and wing-tips controls its balance with nice precision.
The buzzard saw me, too, and began to twist its head and to twitch its wing-tips nervously.
A cormorant, flying so low that its wing-tips broke the water, sped across our bows to some far resting-place.
