Former President George H.W. Bush was honored with a 21-gun salute before his casket departed Texas for Washington, D.C. Monday morning.

At 94 years old, Bush died at his Houston home on Nov. 30. The nation’s 41st president is coming back to Washington, D.C., where he will lie in state at the Capitol rotunda and be honored with a service at the Washington National Cathedral.

Before boarding Air Force One, Bush was honored with a ceremony that included a 21-gun salute and a military band that played "Hail to the Chief." More than 100 people gathered to see the former president off from Houston’s Ellington Field.

An American flag and one with the presidential seal flew nearby.
