Hmmm... Fireworks use Black Powder.. which (unlike modern Smokeless propellant) IS actually an "Explosive"*... (not a terribly efficient/powerful one of course) but an explosive nonetheless...

* classified as "1.1D" on the NATO system IIRC...



Wonder if that's why the "puffer" machines alarmed? They actually worked????

You won't be alone, comrade!

I've already sent such letters to the mayor, airport manager, and convention bureau in STL.

Since it's now been 2 months since the TSA Contact Center promised I would hear from a customer service manager at SAN regarding my 30 minute detention for declining the free cancer dose, I will be giving the leaders of San Diego some "nice" letters, as well.

CalVol, keep it up!

Well, except they didn't apparently detect drugs. Or large wads of cash. Or campaign contributions. Or blank checks.

Well, I think it is a big deal when I had to waste an extra 20 minutes of my time getting the extra attention...(this after being made to wait about the same for the original grope)...and I really think it is a big deal when the TSO put his hand on my pennies!

It's also a big deal that my tax dollars are being used to abuse to me and anyone else who happens to want or need to fly!!!

Then throw in the cavalier attitude of the folks paid to abuse us and, well, I better stop now before being sent to the penalty box.

Black powder is covered under the same exemptions to explosives laws as smokeless. Neither are considered to be under explosives control in "normal" quantities, which for black powder was 50 pounds.

NO result...

So.. from that experience.. I wouldn't be real concerned about flying after being at the range!
I have a good friend that used one backpack for a year carrying mines, grenades, and C4. A month later he used it as a carry on and the TSA's swabs didn't find anything.

I'm convinced that the machine is just a random number generator.

It can eh? Can you provide us with a link to such technology please? I for one would be very interested in reviewing the technical specifications.
I can't believe the TSA machine wouldn't like a few "wins" under it's belt related to the scanners/puffers/etc. I don't think they've been any, can you recall one?

As for proven "technology", they're called D-O-G-S. As they are a highly mobile and effective deterrent and screening force; why would we invest otherwise?

But the ETD did alert on my camera bag that has been nowhere near anything remotely explosive or hazardous.

Just another page out of the play?

Michael Chertoff isn't selling any. That's why.

I had a swap alert in MIA a couple months ago. TSO walked over to the other machine. It gave an all clear and I was on my way.

bingo! Look up the political donations given by L3 corp over the past several years.

L3 is just one of the defense companies that has co-opted our congress and that is why you should expect to see a succession of rollouts of more and more "crowd control" types of technology.

You cannot make a lot of profits growing and training the D-O-G technology.

If you have fired a weapon, wash your hands with hydrogen peroxide.

Isn't peroxide based components one of the chemicals that TSA is looking for?

For example one brand of contact clearner is peroxide based and TSA will alert on it and confiscate the item.

Maybe a little toluene or powdered ammonium nitrate would work better than the peroxide?

Heh, they've swabbed my range bag several times, and never caught anything. I'm just about convinced that the tell the machine what result they want it to return.
