Welcome to our forum.
It's a thermal pane Coleman, so it is lighter, thus thermal panes can fly.........
There were gale force winds that blew buildings down yet the cover is still with the spa?
I had the same thought............ as well as the roof appears to be in very good condition, and the pallets are rather neatly lined up.Any one wanna bet this is simply a picture of a spa being delivered to a difficult location and is being carried in over the roof?It is "possible" it was in a sheltered location, the wind blew back only 1/2 the cover, and it's being held to the spa with a single tie-down strap.
