Fishermen and pleasure boats got a treat after a member of the US Navy Blue Angels aerial aerobatic team made a high-speed pass right in front of them.

The manoeuvre sent a huge water vapour cloud radiating from the F-18 fighter during an air show in the San Francisco Bay area yesterday.

Would've been funny if it got caught in a net.

I'm with you.

It is an interesting photo . . . generally, in order to take a photo of something moving fast like that, you have to use a really fast shutter speed. And if you use a fast shutter speed, I wouldn't think you'd get the kind of motion blur that's showing on the boats in this picture.

glatt · 10-09-2007, 11:16 AM

I think the photographer was panning with the jet and also using a pretty high shutter speed.

Or maybe it was photoshopped. I tend to believe it's real though. Even though it looks unreal.

I"m with you on that glatt. It was exactly what I was thinking as I was looking at it.

That is correct. That's how you get the subject sharp and in focus and blur the background. Used heavily in automotive racing photography. If you use a slower shutter speed and pan the camera with the subject, the background will be blurred while the subject remains sharp, giving the photo a sense of movement and speed instead of what looks like a car just sitting on the track.

From MM's link:

similar but not identical. why bother to shop another?

There are a few more at MM's link. Apparently they do this at air shows a lot.

Quote:

During the US Navy Blue Angels demonstration at the Fort Lauderdale Air and Sea Show at Fort Lauderdale Beach, Florida in May 1998, one FA-18 "Hornet" makes a low pass at nearly 750 MPH (near the speed of sound) to startle the crowd. In this picture, the jet creates a visible shock-wave that envelopes part of the airplane and leaves a white trail of spray in the sea surface from the violent shock wave. You cannot hear the airplane until after it has passed with a loud bang or "boom". The aircraft here cannot fly any faster because the shock waves will break windows in Fort Lauderdale, so the pilot just nudges his airspeed to just under MACH 1.0 to create a small shock wave (that will dissapate farther from the plane) to "wow" the spectators. Very cool to see, and hard to get on video!

Not BS, I've seen this in person when I was a kid living in southern California at the Miramar air shows (though that was over ground not water). These guys are so damn good it is mind blowing. And yes that cloud is water vapor, you can see the same sort of thing when a jet is at high speed and suddenly changes to a high angle of attack.
You can see the water vapor starting to shake off here:

Which then turns to this:

Also called "pulling vapor".

Those telephoto pictures are also very deceiving as to how close the jet was to the boats and spectators. Judging distance between two objects laterally in a telephoto image is next to impossible, so often it appears as if two objects are much closer than they actually were when the image was captured. I very much doubt anyone was close enough in reality to get hurt by the jet's repercussions. The Blue Angels are extremely professional and would never pull a stunt that would endanger the public so recklessly.

I googled around to see if there was backup for this. In the process, I found this page, which has some really nice Angels pics.

This page has a similar pic with an AP byline. So I'm guessing the photo is valid.
