How fast do planes fly?

NASA states that small planes can fly up to about 350 mph, while subsonic planes, which include the jets that carry the majority of air traffic passengers, fly from about 350 to 750 mph, as of 2014. Supersonic planes can fly at speeds up to 3,500 mph.

Crop dusters and seaplanes are examples of small planes that travel from about 100 mph to 350 mph. Subsonic craft have more powerful engines that enable them to fly with heavy loads. The space shuttle and other types of rockets are classified as hypersonic and can fly at speeds of up to 7,000 mph.
