It's already testing a new type of engine it says will eventually be capable of reaching Mach 5 (over 3,000 mph). The engine is designed for a small, unmanned hypersonic aircraft Hermeus is currently creating for the US Air Force, but scaled to a bigger size, it will be able to power a passenger plane.
Superfast Military Aircraft Hit Mach 20 Before Ocean Crash, DARPA Says. Despite the problem, the aircraft reached speeds around Mach 20 (about 15,000 mph) and was able to control its flight for several minutes, officials said.

Bullets vary. Some guns are designed with very slow bullets to make them quieter, which will be around mach 0.9 to 0.95. The vast majority of guns are somewhere between mach 2–3, with very high powered rifles and cannons being in the 3–4 range and lower powered pistols tending to be 1–2 times the speed of sound.
about 3,800 mphThe plane is fast, but it could have been even faster. “We settled on Mach 5 version,” says Kevin Bowcutt, Boeing's senior technical fellow and chief scientist of hypersonics, noting that exceeding Mach 5, or about 3,800 mph, requires far more advanced engines and materials.

Most airliners currently travel around anywhere from Mach 0.6 – Mach 0.9. Military jets of course can travel in some cases at hypersonic speeds. When you do travel greater then Mach one you break the sound barrier and the air around the plane starts to form shock waves.
Mach 15 is about 5104.35 meters per second. The X-43D was envisioned to be able to reach Mach 15. However, it never proceeded beyond the feasibility study phase. Astronauts reach well over Mach 15 during re-entry: they can reach speeds as high as Mach 25.
Absolutely not. Just to be clear, Mach 20 is 20 times the speed of sound in Earth's atmosphere at 20 degrees Celsius which is 24,696 km/h (approximately 15,345 mph). The speed of light, on the other hand, is over 299,792 km/s (remember, that's per SECOND), or 186,282 mi/s.
NASA's scramjet hurtles to earth at Mach 7. An experimental aircraft smashed the speed record for a jet plane on Saturday, flying at seven times the speed of sound. NASA's X-43A craft flew under its own power for ten seconds, reaching speeds of more than two kilometres per second.
“Can a gun fire underwater?” Absolutely! Gunpowder contains oxygen - a key element in the firing process - so when the trigger is pulled, the gun still goes off exactly as it would on land as long as no water has crept inside the shell casing.
3,800 miles per hourThe term “hypersonic” describes any speed faster than five times that of sound, which is roughly 760 miles (1,220 kilometers) per hour at sea level, meaning these weapons can travel at least 3,800 miles per hour.
The NASA/USAF X-15 is the fastest fighter jet ever produced. It reached record top speed of Mach 6.72 or 4,520 mph, which is more than five times the speed of sound.
speed of lightDarkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
The speed of light is sometimes referred to as the “cosmic speed limit”. Light travels in a vacuum at 186,282.4 miles per second or 299,792,458 meters/second.
1. Erich “Bubi” Hartmann. Erich Hartmann is the most successful fighter pilot of all times – with 352 kills. A number that will never be surpassed.
It's physically possible for a commercial jet to get from one side of the US to the other in less than five hours: British Airways' Concorde made it in three hours and 55 minutes on its retirement journey from New York to Seattle's Museum of Flight (and if you're really in a hurry, military jets have made the journey
A flechette (/flɛˈʃɛt/ fleh-SHET) is a pointed steel projectile with a vaned tail for stable flight. Delivery systems and methods of launching flechettes vary, from a single shot, to thousands in a single explosive round. The use of flechettes as antipersonnel weapons has been controversial.
Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.
10^8 meters per secondThe best results, at the present time, tell us that the speed of gravity is between 2.993 × 10^8 and 3.003 × 10^8 meters per second, which is an amazing confirmation of General Relativity and a terrible difficulty for alternative theories of gravity that don't reduce to General Relativity!
There is something called the coefficient of diffusivity of air which estimates the value of this speed to be about 0.2cm/s in standard conditions, which is almost neglegible when considering wind and air flow due to convection currents which are much greater than 0.2cm/s even in a room, and the rate of this airflow
According to The Flash, Allen's top speed is Mach 3.3, or 2,532 miles per hour.
