The TATP explosives allegedly used is a red flag to those of us familiar with these events. TATP was allegedly used by Richard Reid (the "shoe bomber" moron), the London 7/7 bombers and the Paris bombers.

Making a quantity of TATP sufficient to bring down an airplane is not quite as simple as ducking into the toilet and mixing two harmless liquids together.
First, you've got to get adequately concentrated hydrogen peroxide. This is hard to come by, so a large quantity of the three per cent solution sold in pharmacies might have to be concentrated by boiling off the water. Only this is risky, and can lead to mission failure by means of burning down your makeshift lab before a single infidel has been harmed.
But let's assume that you can obtain it in the required concentration, or cook it from a dilute solution without ruining your operation. Fine. The remaining ingredients, acetone and sulfuric acid, are far easier to obtain, and we can assume that you've got them on hand.
Now for the fun part. Take your hydrogen peroxide, acetone, and sulfuric acid, measure them very carefully, and put them into drinks bottles for convenient smuggling onto a plane. It's all right to mix the peroxide and acetone in one container, so long as it remains cool. Don't forget to bring several frozen gel-packs (preferably in a Styrofoam chiller deceptively marked "perishable foods"), a thermometer, a large beaker, a stirring rod, and a medicine dropper. You're going to need them.
It's best to fly first class and order Champagne. The bucket full of ice water, which the airline ought to supply, might possibly be adequate - especially if you have those cold gel-packs handy to supplement the ice, and the Styrofoam chiller handy for insulation - to get you through the cookery without starting a fire in the lavvie.
Easy does it
Once the plane is over the ocean, very discreetly bring all of your gear into the toilet. You might need to make several trips to avoid drawing attention. Once your kit is in place, put a beaker containing the peroxide / acetone mixture into the ice water bath (Champagne bucket), and start adding the acid, drop by drop, while stirring constantly. Watch the reaction temperature carefully. The mixture will heat, and if it gets too hot, you'll end up with a weak explosive. In fact, if it gets really hot, you'll get a premature explosion possibly sufficient to kill you, but probably no one else.
After a few hours - assuming, by some miracle, that the fumes haven't overcome you or alerted passengers or the flight crew to your activities - you'll have a quantity of TATP with which to carry out your mission. Now all you need to do is dry it for an hour or two.
The genius of this scheme is that TATP is relatively easy to detonate. But you must make enough of it to crash the plane, and you must make it with care to assure potency. One needs quality stuff to commit "mass murder on an unimaginable scale," as Deputy Police Commissioner Paul Stephenson put it. While it's true that a slapdash concoction will explode, it's unlikely to do more than blow out a few windows. At best, an infidel or two might be killed by the blast, and one or two others by flying debris as the cabin suddenly depressurizes, but that's about all you're likely to manage under the most favorable conditions possible.
We believe this because a peer-reviewed 2004 study in the Journal of the American Chemical Society (JACS) entitled "Decomposition of Triacetone Triperoxide is an Entropic Explosion" tells us that the explosive force of TATP comes from the sudden decomposition of a solid into gasses. There's no rapid oxidizing of fuel, as there is with many other explosives: rather, the substance changes state suddenly through an entropic process, and quickly releases a respectable amount of energy when it does. (Thus the lack of ingredients typically associated with explosives makes TATP, a white crystalline powder resembling sugar, difficult to detect with conventional bomb sniffing gear.)
It's been claimed that the 7/7 bombers used it, but this has not been positively confirmed. Some sources claim that they used C-4, and others that they used RDX. Nevertheless, the belief that they used TATP has stuck with the media, although going about in a crowded city at rush hour with an unstable homebrew explosive in a backpack is not the brightest of all possible moves. It's surprising that none of the attackers enjoyed an unscheduled launch into Paradise.
So, assuming that the homebrew variety of TATP is highly sensitive and unstable - or at least that our inept jihadists would believe that - to avoid getting blown up in the taxi on the way to the airport, one might, if one were educated in terror tactics primarily by hollywood movies, prefer simply to dump the precursors into an airplane toilet bowl and let the mother of Satan work her magic. Indeed, the mixture will heat rapidly as TATP begins to form, and it will soon explode. But this won't happen with much force, because little TATP will have formed by the time the explosion occurs.
Secrets, Spies and 7/7 by Tom Secker and Terror on the Tube by Nick Kollerstrom go into more detail about the problems with TATP.
"The first reason is that the story has changed so much over time, from military explosives to homemade explosives and then from one recipe to another. There are many contradictory statements on whether HMTD, TATP or some other peroxide-based explosive made up the main charge. The idea of piperine, black pepper and/or Masala spice being part of the recipe was not mentioned until years after the bombings, even though they should have had the evidence within days (or at most weeks).
There are significant differences between the testimonies on what explosives were found and where, depending on which proceedings you look at. Some of this testimony was given during the inquest into the death of Jean Charles de Menezes. A former army man who works as an explosives officer for the MPS was known as Codename NEIL' at the Menezes inquest. He said that the main charge of the explosive was a form of organic peroxide, but said that in his army experience he had never used peroxide based explosives. NEIL said that, If you were to put your hand on a small amount of organic peroxide explosive it can cause it to detonate. So it's just far too unsafe for us to manufacture.' Far too unsafe for an army explosives expert, but safe enough for an amateur home-based bomb-maker?"
