So first we are told:
Anti-terrorist authorities in Britain and the United States declined to describe the bomb design in the foiled plot — whether it was primarily liquid or, more likely, contained liquids in a more complex ingredient list.But as Peggy Noonan said in a different context, "Is it irresponsible to speculate? It is irresponsible not to!"
So how many scary but incredible, unlikely and speculative bomb scenarios can AP pack into one little news story? Let's see:
...Even a battery-operated watch would provide enough power for a detonator. All you need is one shock ...Well, I guess we'll all just have to take the bus from now on. Er, maybe not ...
baby formula ...in powdered form, it can provide a good vehicle for masking crystallized explosives . . .
an Algerian man was convicted of possessing 25 computer disks detailing how to bring down an aircraft using, among other things, crystallized explosives hidden in a container of talcum powder.
During that trial, FBI explosives expert Donald Sachtleben testified he built and detonated three bombs based on the instructions found in the Algerian's home . . .
a likely terrorist scenario would involve a two- or three-member team boarding the same flight, each carrying a different part of the planned bomb . . .
Critical to conventional bombs is a power source to trigger a detonator. Clonan said cell phones could provide an ideal power-timer unit for a bomb . . .
to puncture an aircraft's fuselage would require an explosive charge "half the size of a cigarette packet," . . .
"liquid bombs" were not the most likely explosive. He said it was far more likely a terror cell would try to smuggle on an explosive in crystalline or powder form and to combine it with an acid-based compound . . .
terrorists might also construct an on-board incendiary bomb based on paraffin or gasoline, which if ignited in mid-Atlantic could destroy an aircraft before it could land . . .
Hands-on inspection is the only way to tell if a dark-plastic medicine vial really contains what it says on the label. "You'll have to carry your prescription and prove to security that the medicine really is what it is. But for 20 million people a year going through Heathrow? How do you do that?" Hatcher said, foreseeing a future airport arrivals hall with five-hour security checks.
Even that scenario, he said, could lead to terror attacks — detonating bombs in an airport terminal, not on a plane. "You can carry a bag into the center of an airport with thousands of people around you before you are ever screened. That, too, must change," he said.
