"This story has been blown out of all proportion. The liquids would need to be carefully distilled at freezing temperatures to extract the required chemicals, which are very difficult to obtain in the purities needed."
Once the fluids have been extracted, the process of mixing them produces significant amounts of heat and vile fumes. "The resulting liquid then needs some hours at room temperature for the white crystals that are the explosive to develop." The whole process, which can take between 12 and 36 hours, is "very dangerous, even in a lab, and can lead to premature detonation," said Lt. Col. Wylde.
If there was a conspiracy, he added, "it did not involve manufacturing the explosives in the loo," as this simply "could not have worked." The process would be quickly and easily detected. The fumes of the chemicals in the toilet "would be smelt by anybody in the area." They would also inevitably "cause the alarms in the toilet and in the air change system in the aircraft to be triggered. The pilot has the ability to dump all the air from an aircraft as a fire-fighting measure, leaving people to use oxygen masks. All this means the planned attack would be detected long before the queues outside the loo had grown to enormous lengths."
So instead, because someone somewhere is getting quite paranoid, we now can't bring on water, we can't bring on baby formula, no lip gloss, no makeup, no deodorant. We have longer waits at baggage check because those of us who carry on normally now no longer can (unless we want to buy new products every time we fly). Ridiculous.
