ok i will explain

people on that plane talked to people(by cell phone mainly) watching the news and told them both towers had a plane hijacked a flown into it
now thoe on the plane now hijacked and turning back realized what was what
they tried to take the plane back,
and it went down
period

heros cuase they gave their lives to protect others (in a city)
that clear enough

if u think they shot it down
fuck you
they would have if it got closer to dc,
but it was 20 minutes away
peace
