SAN FRANCISCO (CBS SF) – Space shuttle Endeavour was set Friday morning to make low, sweeping passes over the East Bay, San Francisco, Silicon Valley, Sacramento and Los Angeles following a return to its California roots Thursday.
The shuttle, fixed atop a specially modified Boeing 747 jet, is on the last leg of a wistful cross-country journey that paid homage to NASA workers and former astronauts.
Endeavour swooped out of the desert sky and glided down a concrete runway at Edwards Air Force Base, 100 miles north of Los Angeles, not far from where the now-retired shuttle fleet was assembled.
The shuttle and jumbo jet were scheduled to take off again at sunrise Friday.
