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
Sea turtle Sea turtles are air breathing reptiles that have lungs, so they regularly surface to breathe. Sea turtles spend a majority of their time underwater, so they must be able to hold their breath for long periods.[32] Dive duration largely depends on activity. A foraging turtle may typically spend 5–40 min under water[32] while a sleeping sea turtle can remain under water for 4–7 hours.[33][34] Remarkably, sea turtle respiration remains aerobic for the vast majority of voluntary dive time.[32][34] When a sea turtle is forcibly submerged (e.g. entangled in a trawl net) its diving endurance is substantially reduced, so it is more susceptible to drowning.[32]
