I believe on the Discovery or History channel a few years ago, I saw a
show about a group (IRA?) who told someone of importance what day they
were going to assasinate him. He was travelling in a motorcade, and
sure enough a bomb planted in a bicycle satchel on the side of the
road exploded and destroyed the car, in the middle of this motorcade.
I remember the show saying something like the car spun around from the
force of the blast, and the diplomat bled to death quickly, he didn't
die instantly from the explosion.

But, what I am looking for and thought it was at HowStuffWorks.com
perhaps, was an animation of how that roadside bomb worked. It showed
inside the satchel, a bunch of TNT behind a copper plate shaped like a
C, so when the explosives went off, the "C" of copper  turned inside
out (imagine a backwards "C" now) and turned into a molten bullet
going right at the motorcade, striking the car.

Also I believe the detonator was set off by remote control, so they
could hit the car they wanted in the middle of this motorcade, so one
of the assasins was close by.

In any case, those are all the details I can remember. It was a great
graphic, an excellent graphic! It was a good glimpse of how shape
charges can work, even very crude ones. Just like an RPG shoots a jet
of molten copper through 20" of rolled steel armor :) Let me know if
you have any more questions about it, hopefully someone can find the
graphic!
