You would clearly be able to see a "jolt" from all the videos I have posted.
No, the images are not of high enough resolution, unless the "jolt" was on the order of at least 1/2 second or so long as the upper section hit the first floor below. After that, all hell breaks loose and chaos reigns. You are envisioning a FAR simpler event than actually took place. The "pancake" events could not have been perfectly symmetrical with a perfectly flat meeting of the floors. Only then could you even hope to see the sort of "jolt" you are talking about. The top of the building tilted, as shown by the antenna, so it met the next floor down at an angle. That gives it more of a shearing effect against the lower floor supports, rather that the flat "pancake" effect you seem to envision. That would spread the "jolt" out over some short, but undetermined length of time.
