Endeavour, atop a modified jumbo jet, did a partial loop over the city to honor former Congresswoman Gabrielle Giffords, before it continued its journey west.

Hundreds of people gathered on the grass mall at the University of Arizona campus to watch it pass.

The retired shuttle departed Houston earlier Thursday after a one-day stop at the home of NASA’s Mission Control. It took off Wednesday from its old home in Kennedy Space Center in Florida.

It continues its journey to Los Angeles International Airport, where it’s scheduled to land Friday.

This is the last flight for a space shuttle.
