The chances of capturing a picture like this is so small, a very hard picture to capture indeed!
There is a thing called the internet. it's great. and you know what. It can also be used to research information on all sorts of things. Not
just Kittehs!! 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.
n humid air, the drop in temperature in the most rarefied portion of the shock wave (close to the aircraft) can bring the air temperature below its dew point, at which moisture condenses to form a visible cloud of microscopic water droplets. Since the pressure effect of the wave is reduced by its expansion (the same pressure effect is spread over a larger radius), the vapor effect also has a limited radius.
