The pivotal airplane voyage in the movie Flight includes an early interlude in which the airplane encounters some extreme turbulence. To get out of the turbulence, the senior pilot (played by Denzel Washington) makes some maneuvers that -- judging by the reaction of his junior co-pilot -- are risky and unusual, and seem to strain the plane. But the maneuvers appear to work, as the airplane clears the turbulence and begins flying smoothly.
Something like 30 minutes later, after the airplane has been flying normally for awhile, it suffers equipment failure near its tail, causing it to crash.
During the investigation that takes up the rest of the movie, no one seems to mention the early turbulence or those risky and unusual turbulence-avoiding maneuvers as a potential cause of the equipment failure. Was there some reason why the turbulence or the maneuvers wouldn't have played a role in the eventual failure and crash?
