Austrian Felix Baumgartner became the first skydiver to go faster than the speed of sound.
The nylon parachute 70 feet in diameter will slow the craft to just under the speed of sound.
For the few who don't know, Yeager's the first human to fly above Mach 1, the speed of sound.
It can fly at up to 2.5 times the speed of sound and is designed for low-altitude, high-speed, precision attacks.
The reality is that business is expected to move nearly at the speed of sound to meet earnings expectations each quarter.
They took photographs and used them to calculate both the speed of flow and the speed of sound within the condensate.
NASA, America's space agency, is paying for an experimental version of Inductrack that will travel at half the speed of sound.
Meanwhile, Boeing's Sonic Cruiser (a futuristic aircraft designed to fly at almost the speed of sound) has not been well received by airlines.
Any plane that flies past the speed of sound creates a sonic boom, which often results in a major noise disturbance over close-by areas.
Their data showed that the speed of part of the condensate exceeded the speed of sound, and they had therefore made an acoustic event horizon.
Though the WaveRider was designed to reach Mach 6, or six times the speed of sound, program officials were satisfied with its performance in the latest test.
Its top speed would be 0.8 Mach that is, 0.8 times the speed of sound or around 600 miles per hour, slightly slower than the coming generation of airliners.
If tests go as planned, it will be the first plane ever to fly faster than the speed of sound on a fuel mix that is half biomass.
To cover that retreat, the company trumpeted its Sonic Cruiser, a futuristic 250-seater jet that would fly close to the speed of sound and clip hours off long-haul flights.
Felix Baumgartner plans to leap from 23 miles above Earth on Sunday, breaking the speed of sound within 40 seconds before free falling for another five minutes or so.
Some navies are already testing rail guns, which use huge amounts of electricity to produce a magnetic field which then accelerates projectiles to many times the speed of sound.
The five-metre-long missiles are supersonic within moments of leaving the launcher, having taken their initial course from the control computer, and accelerate to five times the speed of sound.
As a consequence, the D8.1 would cruise at Mach 0.72 (seven-tenths of the speed of sound) and the D8.5 at Mach 0.74, compared with about Mach 0.79 for a B737-800.
The X-51A WaveRider flew for more than three minutes under power from its exotic scramjet engine and hit a speed of Mach 5.1, or more than five times the speed of sound.
But they have not been widely adopted because they have to be accelerated to Mach 1 (the speed of sound) before the air inside them becomes compressed enough for them to work.
Just last week, our Air Force -- our own Air Force -- used an advanced biofuel blend to fly a Raptor 22 -- an F-22 Raptor faster than the speed of sound.
Viewing the Atlantis orbiter perched on the launch pad and protected by the service structure made it seem very fragile, even though it was made to travel over 100 times the speed of sound.
Work at the speed of sound instead.
ENGADGET: Motorola's RAZR HD LTE coming 'exclusively' to Rogers in Canada later this fall
And a red-faced Boeing was forced to withdraw its Sonic Cruiser, a plane intended to fly at near the speed of sound, after airlines rejected the idea that passengers would pay a hefty premium for such rapid transit.
These waves travel at the speed of sound, but when a jet travels at Mach 1 and above these waves merge into one single shock wave as they cannot get out of the way of each other quickly enough.
Those first eager customers are expecting to get their hands on a plane that can fly up to 12 passengers more than 7, 400km (4, 600 miles) at speeds of up to 1, 700kph (1, 050mph), or 1.6 times the speed of sound, over sea and approved land corridors.
"Together, we proved that a human in freefall can break the speed of sound returning from near space, going through a transonic phase and landing safely on the ground, " said Dr Jonathan Clark, a former space shuttle flight surgeon and the Red Bull Stratos medical director.
BBC: Skydiver Felix Baumgartner fell faster than first thought
Once the light enters the ruby, its speed is slowed down to around the speed of sound (approximately 741mph) and the spinning motion of the rod drags the light with it, resulting in the image being rotated by almost five degrees: large enough to see with the naked eye.
