Ok, ya'll have me convinced that it may not be shopped. I just found it seriously hard to believe that they would be that close.
Color me corrected.

Is it a plane flying low or a speed boat skimming a bit high? :p

One year, I was watching the Thunderbirds at Jones beach LI (Back when they were flying T-38s - that'll tell you how long ago) - one of the stunts was flying INVERTED close to the water - only time I EVER saw one of those guys make a rough move - seems the next wave was a tad taller than he figured - he jinked up about 10 ft or so, because it appeard the wave was going to touch his vertical stabilizer!

Yes - they fly LOW

The LOWEST I've ever seen a picture of was of a SU-27, doing a VERY low pass down a runway - by descriptions, and by the photo, he appears to be about 2 ft off the deck

if the first pic is actually a frame from a film rather than a still shot, the effect of the boats seeming to be so close could be adjusted through the depth of field. In effect, making what seems a long way off, much closer. (or vice versa if that's what you want to show)

From now on I am referring to passed gas as pulled vapors.

narcuul · 10-10-2007, 03:20 PM

That actually is water vapor around the fighter.

It is created by the sudden extreme drop in air pressure behind the compressed shockwave. Since the pressure suddenly drops, the air cools instantly, and because cool air can hold less moisture than warm air, the moisture condenses into visible water vapor, but only for an instant.

When the shape of the object travelling through the air is faster than the speed of sound in the air, the compacted air has no time to dispand and the shockwave stays. That front does not break apart as it expands from the object - if it would, there would be no sonic boom.

I hope this explanation is comprehensible..

There is an interesting analogy to Cherenkov radiation.

I was looking very closely at the pulled vapors. I decided to clean off some artifacts and suddenly a dolphin...

glatt · 10-10-2007, 08:19 PM

that's not a dolphin!

OH yea... I'll be giggling about that for a week. If I'm consequently commited, I'll expect letters from the lot of you.

Blue Angels will be flying around tomorrow, the Miramar Airshow is this weekend, and living at the top of a hill about 5 miles NE of the airfield makes us a convenient landmark for high speed U turns to get back for the next pass. They fly wingtip to wingtip and light off the afterburners as they come out of the turns. We're several hundred feet above the field, so they seem very close.

The windows don't stop rattling or the neighborhood dogs stop howling for three days. It's glorious.

The pictures are real. you can seen the coast guard and the buoy lines the boats stay behind. the flight lane is probably a mile wide like someone suggested. The precision and discipline these guys practice every day puts all of us to shame.

Sweet!

More pulling vapor from an airplane that will NEVER even come close to the sound barrier - I'm not going to imbed it, because it's not mine, and it's kinda large
