Bird, as it can fly, is one of the species in the world that can move fast. Some birds become the fastest bird because they can fly in high speed. Some of them even faster than luxury cruises. You can imagine how some birds can travel in a long distance, even cross continents, to find a better weather when the winter is coming. Their wings is very strong to travel hundreds of mile. We donât include Peregrine Falcon here as Itâs the fastest bird when they are in its hunting dive.
More practical long-range aircraft like commercial airliners or military bombers and transports cannot fly such long distances without stopping or refueling along the way. Long range used to belong primarily to the military, and today's bombers typically have an unrefueled range around 6,000 nm (11,110 km).
