I don't think he was breaking or anywhere near the sound barrier. Our military will not allow it's planes to do that speed that low to the ground in populated areas. 2 if it had been SB or close the camara would have shaken when the shock wave hit, and I assure you it's a pretty good SW that you get when a plane breaks or is anywhere near the SB... still it's a pretty cool video...

Yeah, that wasn't anything even CLOSE to the sound barrier. He was at an idle.
That being said, there is no way he got permission to do that sort of stunt in such a heavily populated area. He was completely out of line.
I wished I could have been there to see it though.

going to an airshow in september, cannot wait! i was up in perthshire the other week and hired a row boat to take the better half out on a loch for a picnic. was a nice sunny day, beautiful scenary and very tranquil until a tornado fighter jet came roaring down the loch at i would guess about 50 feet (felt closer, was probably further) i nearly jumped out the boat

Last spring I was in Ballrat, CA, east of China Lake Naval Weapons Center and I could hear jets, it turned out to be 2 F-18's dog fighting. They were pretty high at first to the point could only hear them overhead, then I could see these two dots getting lower and lower. They were just circling each other in a scissors type move like move just trying to get inside of one another untill they just both broke off and flew to opposite sides of the valley.
It was pretty cool just listening to their engines as they just kept circling each other.

I love the way he just seemingly comes out of nowhere. He's not breaking the sound barrier, but I think he's a lot closer to it than some others in this thread do.
Whenever you have that compression cloud (?????) around the fuselage like that, you're pretty close to the speed of sound.

I spent 5 years working on the F/A-18 in the navy with VFA-151, and just knowing the regulations we had in place for our planes and speeds they were allowed to fly around populated areas... we had a Fly by once on ship where a 2 14s we're going over Mach 1, and it literally caused the entire ship to vibrate and you couldn't follow them they were moving so fast...

If he didn't break it he was close as you can see the vapor cone around the plane, but I didn't hear a sonic boom. Below is a flyby next to an aircraft carrier that DOES break the sound barrier and you hear the sonic boom.

btw, Speaking of sonic booms. Just an interesting fact. When you hear thunder, you are hearing a sonic boom. What happens is when lightning strikes. He heats the air around the lightning to extreme tempertures. (over 20,000 degrees) As most people know, when air warms up, it expands. (see experiment below). The air around the lightning heats up so quickly and so hot that it expands faster than the speed of sound (768mph). When it expands that quickly, it creates a sonic boom!
As an experiment, you can blow up a balloon, then stick it in the freezer for a a little while. When you pull it out it will be smaller than when you put it in. Let it warm back up, and it will expand back to it's regular size.
