Boeing 747 is a Tau'ri aircraft used on Earth for transporting people around the Earth.
History[]
In 2002 during Anubis's attack on Earth, a 747 was used to transport an X-302 hyperspace fighter with the still active Alpha Gate loaded on to bring the fighter up to orbit so that Colonel Jack O'Neill could activate the fighter's hyperspace window generator and bring the fighter far away from Earth which eventually worked, saving Earth from destruction.
