I was seated on a roof balcony at the time, i saw it woosh past but never saw it coming because the rest of the roof.
It was a amazing & scary experience all at once as I've never seen anything like it before...it disappeared in front of my eyes.

It was like 4 large lines of smoke that all joined together a bit like once a plane leaves a trail & it grows then it just disappeared.
