The U.S. military is reportedly developing a hypersonic jet plane that could soar at up to five times the speed of sound — faster than a bullet, which generally travels at Mach 2, or twice the speed of sound. After separation, the Waverider accelerated to Mach 4.8 in just 26 seconds, powered by a solid rocket booster.

A bullet fired straight up, with no wind, might reach a height of 10,000 feet (about three kilometers), but will come back down at only around 150 miles per hour: just 10% of the speed and with only 1% of the energy as the originally fired bullet.
What is the fastest projectile?
USING an experimental gun about 60 feet long, scientists at Sandia National Laboratories have blasted a small projectile to a speed of 10 miles a second, which is thought to be the highest velocity ever reached on earth by any object larger than a speck of dust.
How far can a 22 bullet travel?
“The most common and easiest round to get is the . 22 caliber. It can travel around 1.5 miles at a 12,000 foot altitude,” Paskiewicz said. Many factors go into where a bullet travels like wind, obstacles, weight of bullet and trajectory.
