This is known as the Prandtl-Glauert singularity and makes for some impressive photographs. Things just happen faster.'ДЄs aircraft approach the speed of sound, an interesting phenemomen occurrs in respect of air movement over the wings. The airplane is as comfortable to fly at landing speeds as it is supersonic. Planes that are designed to go supersonic go right through 'the number' without a blink. When you go supersonic, you don't feel a thing. Usually the planes are up too high when supersonic for a visible vapor wave, and since you can't fly supersonic around populations, very few people have caught it stateside. It is a rare and spectacular sight, only visible in humid weather. From the front of the plane, the shock wave appears as a circle, but from the back and sides, it looks like very sharp spikes coming off the plane. 'A shock wave forms on the aircraft when it reaches supersonic speeds. In the book 'The Cutting Edge', an F-14 pilot is quoted as follows: Today, of course, modern fighter jets routinely excceed the speed of sound. In 1951, test pilot Bill Bridegman flew a Douglas Skyrocket to Mach 1.88. In fact, there were three X-1s and the aircraft eventually reached a speed of Mach 1.46. Today the Bell X-1 that first the National Air & Space Museum in Washington DC. A few months later, the first British aircraft to fly faster than the speed of sound was the DH 108 Swallow on 9 September 1948. Although 'Aviation Week' leaked the news in December 1947, the Air Force did not confirm it until June 1948. This was the time of the Cold War and the Americans did not want the Russians to know too much about their military capability, so amazingly news of the breaking of the sound barrier was withheld from the world for over eight months.

In his autobiography, Yeager later commented: 'I thought I was seeing things! We were flying supersonic! And it was as smooth as a baby's bottom: Grandma could be sitting up there sipping lemonade.' The flight was described in the book 'The Right Stuff' and depicted in the film of the book. This time he broke through the sound barrier, the precise speed achieved being Mach 1.015. It was Yeager's 13th flight in the X-1 and the 50th flight by the aircraft. Also it necessitated the use of an improvished piece of broomstick in order to enable him to use it as a lever to lock the cockpit door from the inside. This made climbing down the ladder from the B-29 into the cockpit of the X-1 - an operation performed at 7,000 feet - extremely painful.

Two days before the fateful flight, he had ridden a horse into a gate and cracked two ribs. The West Virginian pilot of the X-1 'Chuck' Yeager was a Second World War fighter ace who had turned to test flying. The X-1 was taken up to 20,000 feet slung in the bomb bay of a Boeing B-29 and then released above the Mojave desert in California. It was painted bright orange because it was thought that this would help the camera and chase aircraft tracking the flight (it was later found that white was a better colour for these purposes). Test pilot 'Chuck' Yeager named the aircraft 'Glamorous Glennis' after his wife. It was two years later before the sound barrier was broken by an American aircraft the Bell X-1. In November 1945, a British jet fighter the Gloster Meteor set a new official world speed record of 606.25 mph. Some British and American fighters may have unintentionally exceeded the speed of sound in an evasive dive and there are unconfirmed reports that the German Me 262 jet fighter managed to break the sound barrier. Technically the speed of sound had probably been broken before that by several Second World War aircraft.

The aircraft was the Bell X-1 and the pilot was Captain Charles Yeager. The first flight at faster than the speed of sound occurred on 14 October 1947.

Mach 1.2 to Mach 5.0 is described as supersonic, while speeds greater than Mach 5.0 are characterised as hypersonic. Less than Mach 0.8 is said to be subsonic, while Mach 0.8 to Mach 1.2 is said to be transonic. The speed of sound is commonly refered to as Mach 1, named after the 19th century Austrian physicist Ernst Mach. At 20,000 feet (6,096 meters), the speed of sound is 660 miles per hour (1,062 kilometers per hour). At sea level, the speed of sound is about 761 miles per hour (1,225 kilometers per hour). The actual speed of sound varies depending on the altitude above sea level because sound travels at slightly different speeds at different temperatures and the temperature varies according to altitude. In Washington's National Air & Space MuseumД«ut what exactly is the speed of sound? In fact, it does not have a precise value.

It was long appreciated that breaking through the sound barrier would present a formidable challenge. Ever since the Wright brothers made the first heavier than air flight on 17 December 1903, man has attempted to fly faster and faster.
