"Testing?"

Somehow, I have to believe that "probing" is the more appropriate term, rather than "testing".

These parts, plus hearing aid or cell phone batteries removed in-flight, plus one or two accomplices carrying the rest of the parts, combined with individual bathroom trips....

[Rushmore Rocks]

You're correct. "Probing" is more appropriate under the circumstances.

Sure wish we would get some moisture here in SoDak. Terribly dry here in the "Hills".

[Cindy]

Yep, interesting.

This guy and most terrorist do not probe.

They are either recon|setting up, testing or they are doing.

Probing is some half cocked nonsense we've made up.

None of that silliness is necessary.

Ramzi Youssef created a bomb that he alone could put together after boarding a plane [with the parts] a digital watch as a timer, diluted nitroglycerine in a contact lens cleaner's bottle. He boarded Phillipines Airline flight 434 and on the first leg of the flight, put the bomb together. He put it in the lifejacket pouch under his seat [26K] and then got off the aircraft.
After the aircrat takes off for it's second leg, the watch's alarm goes off, ignites a filament [of a small broken bulb] that he placed in the nitroglycerine. The very small, simple, compact bomb detonated and killed the man who took the same seat [on the second leg of the flight].

As a terrorist attack, it was a failure. Youssef's intent was to ignite the center fuel tank of the 747 and blow the whole thing [something that happened subsequently to TWA Flight 800 during Youssef's trial for the 1993 WTC attack...draw your own conclusions].

Below are the declassified FBI documents concerning this.
