the only force at work here is gravity.
If you believe that we went to the moon that is.

A quick question for the knowledgable...
This is regarding the discovered passport that CTers think is so important and the FBI don't...
Pre Sept 2001, what identification was required to board a domestic flight in the USA? And if a passport was not required, how common was it for people to carry their passport around anyway?
I'm thinking the image of someone off to the airport to go overseas, desperately looking for their passport because they haven't seen it in six months or a year...
Even some rough info/speculation on this would be nice.![]()
Maybe at JFK, but in MPLS at the time for a domestic flight all you needed was a driver's license or gov't issued picture ID.Again, the hijackers are foreigners - they are SUPPOSED to be carrying their passports.

What if there was an emergency change of plan and they had to leave the country, though? A bit awkward if you don't have your passport with you.Maybe at JFK, but in MPLS at the time for a domestic flight all you needed was a driver's license or gov't issued picture ID.
Freefall vs. terminal velocity aren't entirely relevant with respect to the WTC collapses to begin with. Couple of points:Now, on the freefall thing - we are talking about freefall and Terminal velocity in real world, not lab conditions. The quote is from Sport Parachuting by Russ Gunby, pg 63:
"Sooner or later the speed and friction will balance each other and when the balance of these two forces is reached, the falling object will then have reached a steady falling speed which is called terminal velocity. In atmosphere this takes about 12 seconds and is approximately 176 feet [p]er second or 120 miles per hou[r]. Once terminal velocity is reached, an object will not fall any faster."

No. In fact, in the extras of LC2E at Ground Zero, there's a random loon on camera saying "The same people who killed JFK did this."
Again, the hijackers are foreigners - they are SUPPOSED to be carrying their passports.
I guess I don't know even what this whole passport issue is about, but let me state again for those who missed it above, it is known that one of the hijackers did not have a photo ID when he checked in. He was flagged for extra security, which means that his checked baggage was held off the aircraft until it was confirmed that he boarded.
This is all in the 911-Commission report. You folks know how to get there better than I do (heck, I just followed one of all y'all's links)
