I ran across this video that a passenger on a Greyhound bus in Australia shot last year as they drove past a pretty hot fire. Here is their description:
If your impatient the most intense part is from 1:30 to 2:40, however the beginning sets the scene well and gives it an ominous and dramatic mood so I recommend watching the whole thing 😉 I recorded this from the Greyhound bus on our way from Airlie Beach to Hervey Bay, believe it was close to Rockhampton. The fires were burning all the way down to the road and I could actually feel the heat from the flames inside of the bus. Apparently the fires had been raging for some twenty odd days in the area by then. This capture was made on the evening of 20th Oct 2009.
It is most impressive if you watch it in full screen mode (click the arrows at the bottom-right). And make sure you have your sound turned on. The music sound track, as one commenter on Facebook said, is brilliant.
It appears that firefighters had just ignited a burnout along the road and the wind was pushing it away from the road.
