Some people described it as “burning” on its way down.
“It was falling. And bits were falling off and glowing,” user yycjabs wrote on Reddit.

“My wife thought we were getting nuked.”
Many people suggested it was the sun hitting part of a contrail, the trail of vapour left in the wake of a passing airplane.
Even astronomer Phil Plait guessed as much.
We asked experts at Environment Canada and the Royal Astronomical Society of Canada for their input, but we haven’t heard back. The mystery continues.
