Nicola Saunders, a 45-year-old mum of three, who lives on Wells Road, Knowle, thinks she might have found a possible explanation.
She said: "A couple of weeks ago our neighbours were having a velux window fitted to their roof.
"As stones were falling onto our garage roof, the builder put the large cardboard box that the velux window came in on top of our garage roof to
protect it from the debris.
"Last week, either Thursday or Friday, the day that we had strong winds, I heard a loud bang and looked out to see the cardboard flying through the
air.
"It landed up in the tree in our garden. When I looked out again it was somewhere else in the garden.
"The cardboard was about a metre in length and width, maybe bigger. It may be a coincidence."
Mr Hadlington, 36, said: "It was the freakiest thing I have ever seen in my life. I was sitting in my office and saw it out of the corner of my
eye.
"It appeared to come past twice and the second time I got it on camera. I thought it was a piece of metal but it was too far away to tell."
Does cardboeard ever move through the air like that????
Flying cardboard? I'm sorry but lol. I've thrown cardboard boxes before eg: throwing a flattened cardboard box out of my second story window to land
into a trailer when I was moving house. There was noway that the cardboard box could fly off like shown in the video. Sure, the cardboard would
probably go the distance with some wind, but to have it travel that far in a straight line is hard to imagine. I'm presuming that's the type of
cardboard they are talking about. I would take a big frisbee theory over a flying piece of cardboard.
