Now, readers of Bruce Schneier's security blog are invited to weigh in on the feasibility of such a scheme, given the information that just emerged in court:
The court heard the bombers intended to use hydrogen peroxide and mix it with a product called Tang, used in soft drinks, to turn it into an explosive.Link to Schneier's blog, Link to Daily Mail article
They intended to carry it on board disguised as 500ml bottles of Oasis or Lucozade by using food dye to recreate the drinks' distinctive colour.
The detonator would have been disguised as AA 1.5 batteries. The contents of the batteries would have been removed and an electric element such as a lightbulb or wiring would have been inserted.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
