Fastest Flyers in Nature

The fastest flyers in nature are not some birds, nor any insects with wings, not even humans with all the technology... they are a specie of Fungus!!

But the acceleration of the spores still puts them in a class of their own. "One minute they're standing still on a cow pie, and a millionth of a second later they are travelling at 25 metres per second," said Money. 
His colleagues measured accelerations up to 180,000 g – the fastest airborne acceleration seen in the living world. In comparison, a jumping antelope accelerates at 1.6 g, astronauts experience maximum acceleration of less than 4 g during a Space Shuttle launch, and fleas accelerate at 200 g. Jellyfish stingers are fired at 40,000 g in water.
"The fastest spores travelled more than 1 million times their own 'body' length in one second," says Money. "A 1.8-metre human travelling at 1 million times his or her body length in one second would be travelling at a velocity of 1.8 million meters per second, which is more than 5000 times the speed of sound.
