Dashcam video shows cement truck plowing into Texas school bus, killing boy and man

Harrowing video has been released showing the moment a cement truck in Texas collided with a school bus packed with pre-K students returning from a trip to the zoo, killing a boy and a man.

The video, from front-facing and side-facing cameras, shows the cement truck veering across double yellow lines and crashing almost head-on with the bus, causing the bus to roll over.

Just before impact, someone can be heard crying out, and, as the bus hits the ground, a fireball appears to explode while crash debris can be seen flying around.
