With shrieks in the background, a shocked passenger struggled to recount to an emergency dispatcher how a FedEx tractor-trailer smashed into a tour bus carrying high school students. In other 911 calls released Thursday, other witnesses described explosions after the fiery wreck that left 10 people dead.
The California Highway Patrol released the recordings as investigators returned to the scene about 100 miles north of Sacramento to reconstruct aspects of the crash.
Dozens of injured students escaped through windows before the bus exploded into towering flames just before 6 p.m. April 10.(AP)Find more news related pictures in our photo galleries and follow us on Tumblr
