A couple of years ago, after a long haul overnight, I saw a woman on the other side of the cabin doing her hair.
She was using a Brauhn (sp?) curling tong that used a cartridge of butane. The heat is generateed by using a catalytic converter, so that there is no flame.
I drew this to the attention of the cabin crew and pointed out that not only was it butane gas but it was stored under pressure. When asked to stop the woman in question clearly had no idea how the heat in the curling tong was produced.
X-ray? Security? Health & Saftey?
I have just done a journey with an extremely sharp blade (but less than 2" in length) in my case. I will not tell you what it is or how it happened. But the first sector was an accident, as I had forgotten about this. It was not questioned. So I left it in for the remaining six sectors. No X-ray or hand inspection found it.
Safe Journey everyone/
