From the tail view, in which direction do the vortices circulate around the right tip?

Explanation:
Vortices shed by a lifting wing form a circular flow around each wingtip, with opposite directions on opposite tips. From the tail looking forward, the swirl around the right wingtip appears to rotate counterclockwise. This happens because air moves from beneath the wing around the tip to the upper surface and back behind the wing, creating a rotation that, when viewed from the tail, traces a counterclockwise path around the right tip. The left tip would show the opposite sense of rotation from this viewpoint.
