Mitchell says: 'In 1971 I was 6'2" and probably weighed 195 lbs. and in pretty good shape.' Mitchell was a young vigorous male/college student. Mitchell says after learning what was really going on with Cooper he thought: 'I could have overpowered him'. Key word is "overpowered" him. That puts Cooper as slighter in build, or maybe less physically dominant in presence and demeanor in Mitchell's assessment, especially if Mitchell and Cooper were similar in height. That's an interesting judgment if Mitchell wasn't just boasting as an after-thought?
..... What made Mitchell think he could have "overpowered" the hijacker ?
The following is out of Mitchell's intervue by the museum:
"I told the FBI, you know if I was walking down the aisle and I knew he didn’t…I knew what was going on, and he didn’t have his hand in there,
I was way bigger than him and I could’ve, you know, I could’ve grabbed him and jerked him out of his seat. But I never would have done that. You know, I kept saying that to them. So…
he was slight,..."
Also, standing over someone is stronger than sitting below someone.
He was "slight," yet his face was portrayed as too thin in the sketch? Maybe "slight" means small rather than thin?
