Gliders gain altitude in exactly the same way as birds do —
by using columns of rising warm air.
by using columns of rising warm air.
In places where birds fly in circles and soar without flapping their wings, it's very likely that the air is in motion. It rises, taking flies, birds, and glider pilots with itself. Thus, from time to time, we have the opportunity for such a close encounter, half a second of wing-to-wing flight, and a unique shot.
