I found the link to the following article on Telegraph on Bruce Schneiers blog. From the article:
Terrorists could smuggle the components needed to make a bomb on to a plane in Britain despite restrictions on taking liquids on board, it was claimed.
A television documentary team said it had made a bomb by mixing a series of odourless and colourless chemicals that could be brought into an aircraft by passengers.
Which can make oneself think how to judge security tradeoffs…
