I am a frequent traveler - I have selected one belt because it is proved that does not ring any alarm at the security check in several German Airport (actually it did only once, I think they must have a threshold which can be changed and/or are sensible to meteo condition) anyway I managed to pass regularly wearing this dangerous item also in other European Airport.
My watch is in titanium for the same purpose.
This reinforced me the tough that you are asked to remove your belt (or watch)
to avoid the creation of queue because of people who has to pass twice in the control
because in the first the alarm rings.
Actually sometime - in Germany - I am asked about and I say not to worry, it does not ring.
This looks to be accepted.
One day I am coming back from Tel Aviv - pretty high in security - with connection in Wien,
in Tel Aviv I pass without problem in Wien I am asked if I have a belt.
"do not worry" - I say, and I pass
Alarm does NOT ring.
These guys wanted me to remove the belt and pass the belt at the x-ray,
a belt which did not ring first place.
At least they apologized saying that these were the rules.
Anyway while waiting my flight I notice the interesting .. personality .. of a girl,
very tall, possibly a 175 / 180 cm - nice miniskirt and a couple of quite high stiletto heels.
Examining more closely (for scientific purpose only, of course :-)) the shoes
I thought that in principle she could remove/tear the heels and easily kill/hurt someone.
Ah, last but not least - security check - late night, connection from long haul flight,
guy in front of me is really wear out - take off his bottle of water, shows to security
and says that he is thirsty and has to drink.
Security says no problem, so the guy take the bottle, drink and then board the plane with me.
Now, if half a liter of water is dangerous then it is dangerous also if just ingested,
and how about some liquid explosive ?
I wanted to challenge the security but the poor guy was tired so maybe i would have not understand the joke, but anyway...
