The narrative follows specific documented actions, such as Todd Beamer's 'Let's roll' call leading the charge, Mark Bingham subduing a hijacker with a fire extinguisher, and the plane's eventual crash in Shanksville, with title cards noting the timing of military shoot-down orders. Casting prioritizes authenticity, including real FAA official Ben Sliney playing himself and actors portraying actual passengers and crew based on family-provided details like clothing and mannerisms, without any alterations to established real individuals for diversity quotas.

Greengrass explicitly avoided political statements or explanations, focusing instead on the bewilderment and human responses during the hijacking. Reception centered on its raw realism and emotional impact rather than ideological debates, with minor controversies limited to the portrayal of one German passenger's alleged appeasement stance, which drew family objections but no accusations of modern activism. No elements of identity politics, systemic oppression critiques, or DEI-driven changes appear in the premise, characters, or production intent.
