The explosive charges would have been hard-wired to their detonators. The detonators would have all been hard-wired to a central control panel (nothing fancy if you've ever seen one, and it would have had to have been custom made, and large).
I know you'll ask why not radio controlled or cell phone controlled detonators. The answer is that radios are unreliable a lot of the time when used with explosives, mostly when you need them not to be unreliable. Once armed they can go off prematurely due to cross signal interference which can be caused by a ton of different things in a busy office building. If it was CD, those planning the demo would have had to plan for THOUSANDS of NYPD and FDNY radios crowding into a narrow geographic location and jamming their radio controlled detonators.
We know that radio communication at the WTC was crippled from the half-dozen reports made after the attacks, and at least to reports made after the 1993 bombing where the city was criticized for a crappy radio system.
So, you have 3 extremely tall buildings hard-wired with at least 3 miles of copper wire, hundreds of blasting caps, and a couple thousand pounds of a very specific explosive. Flying a 767 into the middle of that wrecks most of your wiring. On the upper floors above the impact, and immediately below the blasting caps would have been yanked out of the charges. In the case of WTC2 you've lost a third of your boom boom. All of those unexploded charges would have been recovered after the fact.
None were. And had all of the charges survived the plane strike, the wiring would have been recovered. No such wiring was recovered.
Check & mate.
