What the bomb could have done

The Times asks experts how large the explosion would have been:

The “patio gas” bomb defused in Haymarket would have generated a fireball the size of a house and a shock wave spreading out over a diameter of at least 400 yards, explosives experts said today.

The propane cylinders and petrol used in the device would have triggered a huge conflagration, as well as causing shrapnel and blast injuries from the exploding car chassis and the nails packed around the bomb, according to Hans Michels, Professor of Safety Engineering at Imperial College, London.

Just one 13kg propane canister — the type sold by Calor under the brand name “Patio Gas” — would release a highly flammable cloud of vapour that would spread over an area of 50 to 60 cubic metres before igniting into a still larger fireball, he said.

“The vapour cloud from one cylinder would fill the order of a big room, and when it ignited the effect would be even bigger,” Professor Michels said. “In addition to the power of the explosion and the shrapnel, you would get a fireball the size of a small house.”

But there’s one huge piece of good news: Expect arrests.

The recovery of the intact bomb will also help forensic scientists to trace the bomb-makers, Professor Michels said. Propane cylinders carry a serial number which can be used to find the point of sale, and isotopic analysis could be used to trace any flour used in the main explosive charge.

Sure, they may have filed off the serial numbers. But maybe not. These guys have proven to be not the sharpest knives in the drawers.

  1. The main reason they’ll get the guys is that a: they have very good pictures because you can’t move in London without a thousand cameras seeing you and b: the police have even arrested and released at least one of these guys.

    And of course within hours we’ll have the usual nutjobs claiming this was a government job to scare everyone.

  2. Let’s hope these people are found, arrested and tortured to death.

    But knowing the British, they’ll probably return them back to their terrorist leaders in exchange for a kind word (which will be withdrawn in the Arabic-speaking news media.)

  3. Already did, Brian. Go check out the Telegraph link in my previous post, and read the talkbacks.

    There is no doubt in my mind that England and the USA are going to be hit hard again. Then the manure is going to hit the fan !!

    Even if they file off the serial number, there are techniques to retrieve them. One reason is that when they file off the numbers, they usually stop after the ink is removed, but the numbers are still stamped into the metal.

    What a surprise! The BBC is referring to the scum who did this as terrorists. It seems as though only Jew killers are militants, according to the BBC.

    I just read Hugh’s comment… I have to say I have some smpathy with his views… the bleeding bbc so politically correct they wouldn’t know correctness if it slapped them round the chops! just bc they’re the biggest news gathering organization in the world most probably doesn’t give them licence for this bias

    Why worry about getting caught when you’re going to blow yourself up?

    Robert:

    These attempted murderers left the explosives there (apparently) intending to set them off later either remotely or using a dupe. The ones behind the murder attempts are very careful not to be in harms way themselves.
