he video is a nice and consise adressing of a few of the issues concerning WTC 7.
Why indeed have explosives go off several hours before the building actually fell?
If the explosives went off prior to WTC 2 falling then why did no one near the building notice that?
If the explosives went off after WTC 2 fell but before WTC 1 fell, again, why did no one nearby notice that happen?
In fact the only one speaking of an explosion inside WTC 7 is Jennings who states that he had no knowledge of what was happening outside at the time he experienced that 'explosion'. Indeed he was, at the time, in the fire stairs and fire stairs have no windows.
Nice catch that Jennings has the order in which the towers fell wrong. I assume he knows which one fell first and is refering to 'the first tower to fal' and 'the second tower to fall' but his faux pas raises doubt as to the veracity of his history. At best he is just not that good a witness in that he does not consisely relate his experiences.
So we are left with the one other choice about when this anomalous 'explosion' occured. It coincided with the fall of one of the towers in which case Jennings testimony is no proof of explosives given that the collapse of a 110 storey building is quite likely to mimic an explosion in a nearby building when the witness has no knowledge of what is occuring beyond the walls of a fire stairwell.
