Mass murder in the skies: was the plot feasible?

Or, just how stupid do they think we are?

Mass murder in the skies: was the plot feasible? [printer-friendly] The Register:

Binary liquid explosives are a sexy staple of Hollywood thrillers. It would be tedious to enumerate the movie terrorists who've employed relatively harmless liquids that, when mixed, immediately rain destruction upon an innocent populace, like the seven angels of God's wrath pouring out their bowls full of pestilence and pain.

The funny thing about these movies is, we never learn just which two chemicals can be handled safely when separate, yet instantly blow us all to kingdom come when combined. Nevertheless, we maintain a great eagerness to believe in these substances, chiefly because action movies wouldn't be as much fun if we didn't.

Now we have news of the recent, supposedly real-world, terrorist plot to destroy commercial airplanes by smuggling onboard the benign precursors to a deadly explosive, and mixing up a batch of liquid death in the lavatories. So, The Register has got to ask, were these guys for real, or have they, and the counterterrorist officials supposedly protecting us, been watching too many action movies?

We're told that the suspects were planning to use TATP, or triacetone triperoxide, a high explosive that supposedly can be made from common household chemicals unlikely to be caught by airport screeners. A little hair dye, drain cleaner, and paint thinner - all easily concealed in drinks bottles - and the forces of evil have effectively smuggled a deadly bomb onboard your plane.
