I was at the range one day working on cold bore shots. I'd shoot one shot and then shoot my .17 hmr for about 15 minutes, then shoot the 6.5 again. RO came over as saw me shooting the rimfire and told me it wasn't allowed. He said something similar. I laughed, told him lets walk down and look at the target, the group is just over an inch. He decided I could keep shooting it.
It literally doesn’t matter what you object you’re speaking about.
People have literally broken the sound barrier with their OWN BODIES, and suffered no ill affects.
Have to zero on a house of cards instead. They’re impervious to pressure waves.
They can't hit head on. It has to be a near miss from opposite directions or it doesn't work.
It's caused when the bow wave can no longer propagate upstream ahead of the body. There is a velocity transition across the shock wave that results in both higher static pressure and temperature behind the shock wave than in front, but with a commensurate decrease in dynamic pressure.
RR Olympus and and his friend, variable intake ramp, would like a word with you.
The Valkyrie got there first. The xb-70 was retired the year concorde first flew.
Thank you for your informed response. Since we are talking about supersonic flight from a sharp-nosed object, I didn't think a bow wave would apply here. My observation was that I wouldn't want to be standing within inches of this (pic below) when it passed by. To me, the question would be whether or not a .50 BMG shock wave could carry enough energy to be deadly. I don't think it could. As I said, I think he shot the deer through the eyes.

You don't like standing next to clouds?
If you will notice, there is a lot more happening around this aircraft than just "clouds." Look at what is happening in the water behind and 30 feet below it. If nothing else, though momentary, I don't know what that much instantaneous pressure differential would do to you if you were within inches of it. It would be interesting to see what Mythbusters said about it. I'll make the time.
Here's something interesting regarding a supersonic cannon-fired shock wave. From the article:
Sheesh! You still don’t get it do you? As the saying goes, you don’t know what you don’t know and you’ll never know what you are actually talking about. The ‘shock wave’ they are talking about in that article is actually the muzzle blast and NOT a shock wave caused by the cannon ball. I’ve seen a lot of pig-headed morons that refuse to give up, but never any as slow witted at yourself. Take that as a compliment.
Do you have a reading comprehension problem? There is no cannon ball. I am talking about a wavefront sufficient in size. The .50 BMG likely does not posses this. The supersonic jet does. That's obvious by looking at the photos. The question becomes if you are close enough to the supersonic object to feel the maximum energy of the wavefront, will it harm you.
"Anyone within 30 to 50 meters from the cannon will feel like he's standing in front of a firing squad," said Igor Fridman, president of PDT Agro, who developed the system. "He'll feel and hear the blast, but he won't be hurled to the ground. He'll be able to run away unharmed … and that's the point of this application."
You are not getting hurt from a shock wave made by the cannon projectile. You are getting hurt by the concussive blast released by an explosion. You stand 100 yards in front of it the cannon projectile passing you by inches is not going to hurt you besides the giant shit in your pants

There’s less of a disturbance in the water than my kid’s 10hp tin boat kicks up. Are you STILL on about this?
That condensation is caused by nothing more than a localised low pressure region in a particularly humid atmosphere.

You dont have that option.
Thinking about it now it was probably the popper moving supersonic that was doing the cutting. Will edit.
