Update, anyone?

This time last year I was posting about the alleged plot to blow up aircraft with "liquid bombs" which resulted in airport chaos, disrupted travel plans for tens of thousands of people, and still to this day restrictions on what you are allowed to take on board. But whatever happened to those arrested? Was the threat ever realistic - there were and still are those who are experts in this field saying that it was just not a practical proposition. Isn't it funny how following the initial hysteria, it all goes quiet? Does anybody have any up-to-date info?
