Sorry Tiger65, but you're spouting nonsense
. All the data supports the fact that it hit allmost fully inverted. Whether it's roll was "only" 150 degree or it was full 180 degree it matters a little. There were two separate FDR's read by separate parities and they both agree.
The "working report" you cite is a a bad joke -- it's purely political job designed to muddy waters to consolidate deceased president's brother's party.
They found some phd from some american university to support their line? So what? Looking deep enough they could also find some phd from some other university claiming parapsychological reasons for the crash. There are some professors claimng and showing "proofs" that 9/11 was a inside job. Same quality of nonsense.
Gentlemen should agree not to use such utter political motivated rubbish as a data source...
