I very much struggle with this. When terrorist want something they are smart enough to figure it out. They are everywhere and plan their actions carefully. A few years ago, it was a granate, then it was a bottle, then your fork and knife, then they figured to make something out of toothpaste, gel and others, now its powder, what is next? who says they are not infiltrated in the pilot/handling/security network. One day they get the call it's their turn.
I am not saying we should not do anything at all, but its getting silly now. in the future you have to be 6 hours in advance to catch a flights. The cost involved in this is enormous. This morning I heard on the news the security of the countries were aware of the buy wanting to blow up the plane but didnt respond. Welll what do you want to do then?
Luckily i make around 90 flights a year, this is going to fun this year.....
