how long do gliders stay in the air
Gliding Glider pilots can stay airborne for hours by flying through air that is ascending as fast or faster than the glider itself is descending, thus gaining potential energy.[17] The most commonly used sources of rising air are
Lovebug Localized lovebug flights can number in the hundreds of thousands. The slow, drifting movement of the insects is almost reminiscent of snow fall except that the flies also rise in the air. Two major flights occur each year, first in late spring, then in late summer. In south Florida, a third (but smaller) flight can occur in December.[5] The spring flight occurs during late April and May, and in the summer during late August and September. Flights extend over periods of four to five weeks.[6] Mating takes place almost immediately after emergence of the females. Adult females live only three to four days, while males live a little longer. They have to stick to each other at all times.[5]
