	To add some real evidence, I saw some vultures circling last
weekend. I watched them for a few minutes and they were flying in
*circles* without *ever* flapping their wings and without losing any
altitude. Now, whatever else is true they *must* have been going
upwind at least *part* of the time, tet they maintained altitude for a
full circle without needing to so much as flutter their wings.
Whatever the mechanism, it *works*, I saw it happen.
