What was the apparent intended target of flight 93?

The flight was scheduled to land at San Francisco, California, but the hijackers were headed towards the White House, as part of the series of terrorist attacks on September 11, 2001.

on 9/11 you had 4 planes 2 of the planes crashed into the World Trade Center and one went to the Pentagon and the 4th one was suppose to go to the White House but the passengers on board were able to get to the cockpit in time to take down the plane before it could get there

this question makes no sense dude
