 Reid's Shoe Bomb Was Likely
  Made by an Explosives Expert

  Other Terrorists Have Used a Similar Device

LONDON -- The bomb that terrorist suspect Richard Reid hid in his shoe, in what the FBI calls a foiled attempt to blow up a U.S.-bound American Airlines flight last month, suggests a knowledge of explosives that probably goes far beyond his abilities, European experts say. They say the device is reminiscent of one commonly used by Palestinian suicide bombers, but more sophisticated.

Arriving on Dec. 22 unkempt and unshaven, without luggage and with a ticket he bought with cash for his Paris-to-Miami flight, Mr. Reid would have made a very unsophisticated terrorist, relatives and acquaintances say -- certainly far less polished than the 19 hijackers who commandeered four U.S.
  jets on Sept. 11 for their suicide missions.

But there was nothing unsophisticated about Mr. Reid's intended weapon: a wedge of plastic explosive dyed black and concealed in the sole of his high-top suede sport shoe. An official of the Federal Bureau of Investigation has confirmed that a highly unstable component known as triacetone triperoxide, or TATP, served as the trigger. Threaded through the plastic explosive and topped with a long, black-powder fuse running up through his shoelace, the TATP igniter would have allowed the British-born Mr. Reid to set off his charge without wires and batteries -- parts likely to be discovered
  by airport X-ray machines.

Mr. Reid was subdued by fellow passengers after a flight attendant saw him using matches in an apparent attempt to ignite his shoe during the flight, by her account. The flight was diverted to Boston,
  where Mr. Reid was arrested and where he remains in custody.

TATP increases the likelihood of premature detonation, so Mr. Reid's bomb wasn't the surest bet, yet Roger Davies, former head of Britain's IRA Bomb Squad, considers its design elegant and says that whoever fashioned the weapon knew what he was doing. "It's clever and very simple," Mr. Davies says. "The best bombs, the most significant devices, are very simple in nature."

Used alone, Mr. Davies says, TATP is favored only by the foolhardy. The concoction, which he describes as the "explosive of last resort," is easily mixed -- it is known as a bathtub explosive -- but less powerful than plastic explosives and far more volatile. Commonly employed by Palestinian extremist groups such as Hamas, TATP can be set off by random sparks and sudden movements. "It's very sensitive," Mr. Davies says, "and it's the main reason these Palestinian groups have lost so many
  bomb makers over the years."

Far stabler is the plastic explosive known as PETN, which the FBI said also was present in Mr. Reid's shoe, serving as the primary charge. Mr. Davies says that "you can burn [PETN] on the stove and it won't go off." The drawback for a would-be bomber is that in its pure form, PETN requires an electrical
  charge to set it off.

Combining PETN and TATP in a single bomb is unusual, Mr. Davies says. A French investigator agrees, saying an explosive mix of the sort with which Mr. Reid boarded is "not classic at all." But the mixture makes sense, Mr. Davies concludes, if the bomb maker is trying to avoid setting off metal
  detectors.

Unlike TATP, PETN is difficult, though not impossible, to come by in Europe, with the Balkans being the most likely source. "He was taught this somewhere," the French investigator says. "He didn't come up
  with it on his own."

The role of TATP in the thwarted attack harks back to other bomb incidents, most notably one aboard a Philippine Airlines flight to Japan in December 1994. In that incident, the explosion didn't pierce the plane's fuselage, as the FBI says Mr. Reid apparently intended to do, but killed one passenger and injured six more as it ripped a hole in the floor. Also in 1994, a pair of TATP-based car bombs were detonated in London, outside the Israeli Embassy and a Jewish philanthropic institution. Two
  Palestinian students later were convicted of conspiracy in the case.

Both Mr. Davies and the French investigator say the TATP in Mr. Reid's shoe suggests a connection to Palestinian extremists, noting that Mr. Reid visited Israel in July. They add that their assessment doesn't rule out Mr. Reid's connection to al Qaeda, the terror network headed by Osama bin Laden, since some Palestinian extremists are closely allied with the organization.
