, or Mach 6.
Speed of Sound
won their first regional contest in Spring of 2012 and have been working toward the International title ever since - Peggy Jones (bass), Debbie Landers (tenor), Carter Maysilles (baritone), and Ashley Wright (lead).
At 30,000ft the jets can reach an incredible Mach 2 or about 1,490mph, which is nearly twice the speed of sound

To determine the speed of sound
in air by measuring the resonant frequencies of an open tube.
There are obvious advantages to ramping up to hypersonic flight, which is generally defined as anything that reaches at least Mach 5, or five times the speed of sound
At typical airliner altitudes, the speed of sound
is about 1,060 kilometers (660 miles) per hour.
If successful, the Red Bull Stratos mission hopes to establish four world records: the first human to break the speed of sound
, without a vehicle; the altitude record for manned balloon flight; the altitude record for free-fall; and the time record for the longest free-fall.
Now, a scientist named Stephan Gekle has found that you can make air move faster than the speed of sound
by doing a simple little trick: throw a rock in a pond.
Quantitative ultrasound was used to assess the axial speed of sound
along the distal third of the radius, the proximal phalanx of the third finger, and the midshaft of the tibia.

Brian Clemenson's seasoned campaigner slides down to the basement level for his race this afternoon and, capable of stepping upon recent performances, Speed Of Sound
can score at the chief expense of Raithby Saha.
