# Question: What Can Go Mach 3?

## Can a plane outrun a bullet?

Yes.

Planes can shoot themselves down with their guns.

Strictly speaking the muzzle velocity of the bullets was faster when they left, but bullets slow down with time (due to air friction), falling towards the ground (due to gravity), while the airplane does not – provided it keeps the engine running..

## What is the fastest mach speed ever recorded?

Guinness World Records recognized NASA’s X-43A scramjet with a new world speed record for a jet-powered aircraft – Mach 9.6, or nearly 7,000 mph. The X-43A set the new mark and broke its own world record on its third and final flight on Nov.

## Why do planes not fly over the Pacific Ocean?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

## What is mach speed?

Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).

## Can a 747 break the sound barrier?

As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.

## Are sonic booms illegal?

In essence, that regulation prohibits anyone from operating a civil aircraft at a true flight Mach number greater than 1 over land in the United States and from a certain distance off shore where a boom could reach U.S. shores.

## Is Mach 3 faster than a speeding bullet?

Think about moving more than three times faster than the speed of sound, aka Mach 3. Consider this: It’s more than 33 miles per minute. Somebody call Superman: Joersz and Morgan literally flew “faster than a speeding bullet.”

## What planes can go Mach 3?

The XB-70 Valkyrie was a unique aircraft with six engines which together could accelerate the 240,000-kilogram aircraft to a velocity of Mach 3.

## How fast is Mach 1 Mach 2 and Mach 3?

Mach Speed is when an object moves faster than the speed of sound. For normal and dry conditions and temperature of 68 degrees F, this is 768 mph, 343 m/s, 1,125 ft/s, 667 knots, or 1,235 km/h.

## What is the fastest jet?

Lockheed SR-71 BlackbirdThe Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.

## Has a car broke the sound barrier?

Thrust SSC holds the world land speed record, set on 15 October 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier.

## How fast is a bullet in Mach?

To put this into context, the average bullet travels about 1,700 miles per hour. Mach 1 is about 767 miles per hour. A railgun projectile will travel at Mach 6 – that’s nearly three times faster than the typical bullet.

## Is a missile faster than a bullet?

Wall said the test missile was traveling 3,200 feet per second, which equates to 2,182 miles an hour. … In comparison, a 9mm bullet travels at about 900 feet per second.

## How fast is Hyper Sonic?

For aircraft speeds which are much greater than the speed of sound, the aircraft is said to be hypersonic. Typical speeds for hypersonic aircraft are greater than 3000 mph and Mach number M greater than five, M > 5.

## Can a fighter jet shot itself down?

The F-11 Tiger is noted for being the first jet aircraft to shoot itself down.

## Who broke Mach 3?

Captain Milburn G. AptUSAF Captain Milburn G. Apt became the first man to exceed Mach 3 while flying the Bell X-2 on September 27, 1956. Unfortunately the aircraft went out of control after making history and he was killed.

## Is Mach 5 possible?

The 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. Plus, it’s not worth it.

## Can a fighter jet fly faster than a bullet?

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.
