The "Sweet
Spot"
Cranes
could travel faster without the ultralight. It is a necessary
partnership for the chicks'
first migration. Why?
Do you see the lead bird? It is only 6 or 8
inches from the trike’s wingtip.
Flying with the plane can help a whooper, particularly
the bird closest to the wing. The ultralight’s wing
creates lift that
gives the nearest crane an easier ride. The bird can soar more
and flap less. That's why pilots say the "sweet
spot" is the position closest to the wing. Birds know it, too.

order on the Web.
