Sound barrier pictures
Actual photos of the sound barrier. This phenomenon only happens at the instant an Aircraft breaks the sound barrier. And it literally appears like the aircraft goes through a wall. I hope you find these pictures as fascinating as I did.

The Grand Canyon Skywalk
GLASS BRIDGE
The Glass Bridge Construction of the Skywalk began March of 2004 and is estimated to be completed by 4th quarter of 2006.
The Glass Bridge will be suspended 4,000 feet above the Colorado River on the very edge of the Grand Canyon. On May 2005, the final test was conducted and the stucture passed engineering requirements by 400 percent, enabling it to withstand the weight of 71 fully loaded Boeing 747 airplanes (more that 71 million pounds). The bridge will be able to sustain winds in excess of 100 miles per hour from 8 different directions, as well as an 8.0 magnitude earthquake within 50 miles. More than one million pounds of steel will go into the construction of the Grand Canyon Skywalk.
