United Flight 93 

The fourth hijacked plane of the September 11th attacks, which was planned to be crashed into either the Capitol building or the White House. This was prevented by the crew, who fought back against the hijackers, causing it to crash in a rural area of Pennsylvania.

The people from United Flight 93 deserve a memorial more than most, because they prevented a plane from crashing into the capitol or the White House.
