What makes me nervous is the use of propane. Remember that London bombing plot three years ago, in which jihadis tried — and failed — to set off a bunch of car bombs around the city? Quote:
The car bombs were similar to highly destructive explosives used in Iraq and could have killed hundreds of people, U.S. and British officials told NBC News. British officials warned that the country was facing a “serious and sustained” terrorist threat…
Authorities believe [the first car] was intended to be set off by remote control by a cell phone found inside. The cell phone had received at least two calls, which should have detonated several gallons of gasoline, but when the calls came in, the bomb failed to go off, the official said.
Had it done so, that blast then would have ignited six to eight tanks of propane in a mist to make a fuel-air explosion, creating a fireball the size of a small house and propelling 18 to 20 boxes of roofing nails around a large area at bullet speed, counterterrorism officials said.
Fuel-air bombs are hugely destructive, as this harrowing Danger Room article published after the London plot broke made all too clear. A fuel-air bomb properly detonated in Times Square on a Saturday night likely would have killed hundreds of people. If that’s what this was — and the feds evidently aren’t sure yet, despite reports of “fireworks” going on in the back seat and someone running away from the vehicle — then there’s a seriously dangerous individual running around NYC right now. Stay tuned. While we wait, check out this PowerPoint presentation generated by the NYPD after the London plot was foiled. The last slide is the one you’re interested in.
