How fast to break the sound barrier in knots?

It’s not possible to break the sound barrier in knots, as the speed of sound in air at sea level is approximately 343 mph, so any speed in knots above that is just a figure of speech. For supersonic planes, the speed of sound is around 1,235 mph, making it harder for aircraft to exceed it.

How do you break the sound barrier in knots?

The fastest recorded knot-breaking speed is 723 mph at which point the air pressure around the aircraft generates a force equal to that of four tons of TNT.

How fast to break the sound barrier in knots and altitude?

A Boeing 747-400 can fly at around 646 mph at an altitude of about 39,000 feet. Needless to say, this is incredibly fast! The fastest any of the military aircraft has been certified to reach this speed is 761 mph.

How fast can you break the sound barrier in knots?

Most people are aware that the sound barrier was first broken in 1986 when Chuck Yeager broke the sound barrier in the C-5A Galaxy. But the first time it was done in knots? That was in 1998 when a U.S. Navy F-18 flew at 667 miles per hour.

How to break the sound barrier in knots?

The first model aircraft to fly faster than the sound barrier was the Bell X-1. This airplane was developed by the U.S. Air Force in the 1950s and was flown by test pilots Chuck Yeager and Bill Dana. Fitted with two additional rocket engines, the X-1 reached a speed of 2,193 miles per hour (3,400 km/h) in October 1947. The vehicle’s top speed of more than six miles per second (9.8 km
