Thanks, but I truly don't care where these urban legends come from or if they are proven incidents. My point is that requiring people to drink out of containers is not an effective security measure.

I think that you are referring to the people in the states who have brought their own water on board and then drank it in front of everyone as to say "Look, I got this past TSA. What a bunch of a**-clowns". I'm not implying that an actual terrorist dry run would be doing this. Of course, they would want to be as low key as possible.

I don't think that the people who have caused diversions have intentionally tried to get it past the TSA and then broadcast that fact; they may have been intentionally trying to circumvent the rules (I suspect that to largely be the case), but then they drink from them in flight.

Can you expand on this second point, Bart? What liquid explosives are drinkable? What components of binary liquid explosives can be drunk when they are in the concentrations required to effectivley mix up a bomb onboard the aircraft?

I suspect it's more along the lines of the fact that containers could have false bottoms, and that there are legit liquid containers (such as medications, shampoo, etc.) that one could not drink from.

That presupposes the governments' allegations about effectively mixing binary liquids onboard are true. Some of us have umm... doubts.

But Bart said the X-ray machines can detect false bottoms. Between that and drinking it, I don't see the problem.
