This is the terrifying moment children scream in terror as a speeding bus hurtles along a road before smashing into river - injuring nearly 20.
Footage from inside the Blustar vehicle show students clinging to the seats on the top deck as the countryside rushes past the windows with horrifying speed.
The teenagers' voices get more and more panicked as they shout down the bus 'we're gonna die. We're actually gonna die. What's he doing? We're actually going to die!'.
They claim the bus has just had a 'major crash and now he's speeding off', while the front window appears to have been smashed.
One woman on the scene said the driver told her the bus's accelerator pedal had jammed and the brakes had failed - which would fit the theory that it clipped another vehicle and then did not slow down as it careered along the road.
