FREMANTLE Herald cartoonist Angie Masefield captured this strange plume as it disappeared into the ocean around 4.30pm on Tuesday (October 8).
“I was on South Street, between South Terrace and Marine Terrace,” Ms Masefield says.
Suggestions it was a jet stream were scoffed at.
“Jet streams don’t land in the ocean, and it was curved across the sky, not in a straight line.”
Calls to the Department of Fire and Emergency Services and the Bureau of meteorology failed to come up with any answers
