Gotta love how Australians report news.
Article
here. Sun shining through bottle of water causes plane fire. ATSB is the Air Transport Safety Bureau. (I used to do paralegal work associated with them years ago.)
"The sun was shining through a water bottle at the side of the cockpit," the ATSB report said.
"The bottle was focusing the sunlight like a magnifying glass on the cover of the cabinet defect log, which began burning."
The bureau did not say whether the water in the bottle was used to douse the fire.
