On which flight did passengers sacrifice themselves to protect the capital on 9/11?

The correct answer pertains to United Airlines Flight 93, which was hijacked on September 11, 2001. Passengers aboard this flight became aware of the hijackers' intentions, particularly after learning that other planes had been used as weapons in the attacks on the World Trade Center and the Pentagon. Demonstrating incredible bravery and resolve, the passengers took action to regain control of the plane, ultimately leading to its crash in a field in Pennsylvania rather than allowing it to reach its presumed target, which was likely the U.S. Capitol. This act of sacrifice saved countless lives and is a powerful example of heroism in a time of crisis.

The other flights were involved in the attacks as well; however, the passengers on those flights did not take the same defensive action as those on Flight 93. American Airlines Flight 11 and United Airlines Flight 175 were used to strike the Twin Towers, while American Airlines Flight 77 was crashed into the Pentagon. The critical distinction lies in the proactive measures taken by the passengers of Flight 93, which were not mirrored by the passengers on those other flights.
