>but because their arms didn’t tire as quickly from operating the flight controls<p>While tiring would be a factor, even if completely fresh, you can simply move a lesser weight (force) faster than a larger one.<p>Second problem is that there were multiple differences between MiGs and Sabres - the one I always heard was most significant, back when I was a teen, is that Sabres were better constructed, MiGs were more likely to fall apart from relatively light damage. So don't take <i>any</i> single article or viewpoint as <i>the truth</i> - reality is always more complex than will fit into a article or book.
