Description
A Royal Canadian Air Force CF-18 Hornet makes a near-supersonic speed flyby at the Cleveland National Air Show.::geek speak follows::
As an object nears supersonic speeds, areas of low pressure form at various points around it due to the shedding of sound waves. If there's enough humidity in the air and/or the temperatures are right, clouds of vapor can be seen. These are known as Prandtl-Glauert singularities.
The speeds at which this CF-18 Hornet was traveling is in the range of what is known as transonic (between Mach 0.8 and 1.2).

I'm still annoyed that I missed the one of one of the Blue Angels doing their low high-speed pass right off the runaway. The burst effect around the jet looked like it was PERFECT... but noooooo... missed it... lol

That was a brilliant shot. The smoke or lighting reflection around it are a nice addition to this well-pictured aircraft.

Thanks! Looking at some other shots of similar craft, I'm seeing that these clouds always seem to set up in the same pattern around this particular jet: [link] .
