The heartbreaking cries of girls who watched their mothers die on Thunder River Rapids ride: Two young girls, aged 10 and 13, were miraculously thrown to safety from the doomed Thunder River Rapids ride at Dreamworld on Australia's Gold Coast and watched in horror as the four adults in their raft were killed. A malfunction with the ride's conveyor belt is suspected to have caused the six-person raft to flip, crushing and drowning two men, aged 38 and 35, and two women, aged 42 and 32, about 2.20pm on Tuesday. Those killed include Canberra woman Kate Goodchild, 32, her brother Luke Dorsett, 35, his partner Roozi Araghi, 38, and another woman. The New Zealand Herald has named Cindy Low, 42, from Kawerau, as the fourth victim. I was really devastated by this event.

I think this is a terrible tragedy because the victims at dreamworld were there to have fun not to die. More needs to be done to test these roller coasters to make sure that it does not happen anymore. Unfortunately it happens too often more than it should and we do not hold these park authorities accountable.

Hello friend. It's with a heavy heart that I'm typing this. The story of what happened to those people is really pathetic and saddening. I feel really terrible about the event. Accidents of such nature are highly predictable and can be easily avoided but because of negligence and greed, operators won't properly maintain their machines. It's just sad

Wow, how sad!  This is truly terrible that this happened.  What an absolutely horrible situation!  I just can't imagine the horror of the people watching as well as those involved.  It must have been a terribly scary scenario for everyone, including the people watching and especially the people involved.  The children who lived will obviously be permanently scarred and have lost their parents which is even worse.  I really found this heartbreaking.
