I imagine almost everyone has seen this picture by now. But I recieved the picture again in my email today (like the 5th time I have had it sent to me), and thought there might still be some people out there who haven't seen it.

quote:Through the view finder of his camera, Ensign John Gay could see the fighter plane drop from the sky heading toward the port side of the aircraft carrier Constellation.

At 1,000 feet, the pilot drops the F/A-18C Hornet to increase his speed to 750 mph, vapor flickering off the curved surfaces of the plane. In the precise moment, a cloud in the shape of a farm-fresh egg forms around the Hornet 200 yards from the carrier, its engines rippling the Pacific Ocean just 75 feet below, Gay hears an explosion and snaps his camera shutter once. "I clicked the same time I heard the boom, and I knew I had it," Gay said.

What he had was a technically meticulous depiction of the sound barrier being broken July 7, 1999, somewhere on the Pacific between Hawaii and Japan. Sports Illustrated, Brills Content, and Life ran the photo.

The photo recently took first prize in the science and technology division in the World Press Photo 2000 contest, which drew more than 42,000 entries worldwide.

A naval veteran of 12 years, Gay, 38, manages a crew of eight assigned to take intelligence photographs from the high-tech belly of an F-14 Tomcat, the fastest fighter in the U.S. Navy.

At sea level a plane must exceed 741 mph to break the sound barrier. The pressure change condenses the water in the air as the jet passes these waves. Altitude, wind speed, humidity, the shape and trajectory of the plane - all of these affect the breaking of this barrier." "The slightest drag or atmospheric pull on the plane shatters the vapor oval like fireworks as the plane passes through," he said. "Everything on July 7 was perfect. You see this vapor flicker around the plane that gets bigger and bigger. You get this loud boom, and it's instantaneous. The vapor cloud is there, and then it's not there. It's the coolest thing you have ever seen."
