Wow, watched the whole thing twice. I have a couple questions I don't get about the planes. What are the two planes that are crashed into the WTC? You know how they compare those two planes evacuation time and everything, what is the purpose of that and how is it also relevent? There's "four" planes but I don't understand any of these four planes. I know the one plane landed in Cleveland, what's this have to do with 9/11?
There were 4 "alleged" planes. One didn't crash in west PA, one didn't crash into the pentagon. The one that landed in Clevland is believed to be flight 93. I don't want to speculate on what may have happened to the original planes that hit the WTC. We dont know. Form eyewitness reports they thought it was a cargo aircraft.
the identities of the planes is still uncertain. lots of people are asking the same questions as you.
check out team8plus.org for well-sourced, but unproven, theories about what planes hit WTC1,2 etc. the cleveland mystery is a theory that bears looking into. whether or not 93 landed there is uncertain. I think LooseChange should be careful to suggest that "93 landed at CLE" represents one possibility, but is not nec the answer.
the basic answer about all 4 flights is is Nothing About Official 9/11 commission Story Fits Data Very Well.
