The passengers were evacuated before this bus fell through a crater in the road and was swept away by rushing flood water.
This unbelievable video comes from Para, in northern Brazil. Flood waters weakened this road so much that it washed away underneath a bus that was driving over it. Luckily, everyone was evacuated in time, but there was no saving the bus. It floated away in the rushing flood, and may very well be in the ocean by now. I just hope another bus didn't come along right after. Just kidding, that never happens.
