TATP can be detonated simply using friction or impact, while most nitrogen-based explosives require a detonator like a blasting cap. TATP is extremely unstable, and while it can be made at room temperature, the heat given off in the chemical reaction to form the product can be enough to set off the material. That is the reason that the reaction is carried out on ice and must be kept below 50°F.
Once made, TATP is a white crystalline solid material which is filtered and then dried at room temperature. The crystalline material is extremely friction-sensitive and must be handled with great care. An accidental shock, heat from a nearby cigarette, or screwing on a bottle cap with trace material caught in the threads all have the potential to ignite the material.
Because of its instability, TATP is usually made just before it is to be used in a bomb. If the material is made and then stored, the crystals are stored underwater in a vessel without a screw cap. Crystalline material left sitting out at room temperature for a period of time will begin to sublime, a process where the solid goes to a gas without passing through a liquid phase, as most chemical compounds do. The gas produced is highly toxic and dangerous.

On October 1, 2005, a young Oklahoma University student sat on a park bench eating a sandwich less than 200 yards away from the OU football stadium, with over 80,000 fans present. Just before the half-time show, his backpack with two to three pounds of TATP inside, exploded. It is not clear what he intended to do with the bomb. However, police believe that it was accidentally detonated by his own carelessness. Law enforcement may see more evidence of TATP explosives here in the United States in coming years.

There's about 400+ people in a carriage during the rush hour...
The explosion happened just after Mr Lait and Ms Main, 23, got on the train at Liverpool Street on their way to the South Bank for a rehearsal.
He recalled that the carriage had about 20-25 people in it, from all walks of life, and aged from their teens to over 60.

20-25 people in a carriage! Most Northern Line regular sufferers (sorry commuters) have heard such things rumoured but never actually seen them.
Even that figure (which I think is far too low) would give us 70+ over the three carriages alone.

With all these things I think the cock-up theory is more likely than the conspiracy and that (IMO) is the reason they're avoiding an enquiry - to cover up the incompetence of the security services / misdirection from a govt keen to downplay the consequences of their contribution to the War on Clutter or over-concerned with being 'PC' where certain parts of our society are concerned.

Some carriages are emptier than others. On the Piccadilly Line out of Heathrow the rear carriages are always fuller than the front becuase that's where the airline passengers board the train.

Again people you're falling for the ranting of conspiracy nuts:
Bomb were detonated by the bombers
Initial reports of explosion under the floor were discredited
Flash burns seen on some of the wounded (and it was only a very small proportion) do not mean it wasn't TATP - these could quite easily be secondary effects from other accelerants.
The power surge was just the initial conclusion of the guys in the control room - a perfectly reasonable conclusion given the evidence they were working with.
No-one has yet to provide any credible evidence to refute the official version of events. Apply a little bit of critical thinking and you'll see plainly that the 'evidence' for the conspiracy is in no way convincing.

Off topic but may be pertinent, why is ok to call people fools, nuts and incompetent but not idiots or stupid arent they all insults?
The 7/7 event was orchestrated by the Goverment as previously stated. The Police story is full of lies and inconsistencies and the Goverment blocked any official enquiry as it said it would be pointless. Now maybe I'm a fool or stupid but if we are to believe this event and it is an event unpresedented in the UK one would assume that the Goverment would want to find out through the use of a public enquiry as to what really happenedbut it chose not to.
How convenient it must of been to be having a anti terrorist exercise the day of the bombings, plenty of time for the perpatrators to escape during the "exercise" and its funny how the same thing happened on 9/11, just a coincidence isn't it.
The 4 alleged bombers were patsies, the poor sods were part of the excercise but someone forgot to tell them that the exercise was for real and they would be made real terrorists.
Its the perfect cover story, you have 4 Asain men with rucksacks caught on cctv and the police anounce to the world that these were the bombers. Well I bet if they showed all the footage that day there would be thousands of simmilar looking men so the pictures prove nothing, again the set up is just like 9/11. One photo released of Asian looking men at a airport security check point and again were told these are the terrorists, that is the proof offered to the Brtish public , 2 photographs used to convince us who carried out these attacks.
Again look at the background of the bombers, average joe's with no previous, not affiliated with any known groups, just normal men who suddenly decide to blow themselves and others up. Yeah I get out of bed everyday with the same thought. When are the doubters going to realise that there is a war going on, its a war against our freedom and liberty, these events are not unique in history, its happened time and time again. Goverments cannot be trusted, Goverments pose the greatest threat to their own people, again this is historic so why do people find it hard to accept. Its not like it hassent happened before, what will it take for those with closed minds to finally open them.
