'UFO' filmed flying over Sheffield - and witness says they have proof it's not a plane

“We were watching planes...then we saw this other thing - and we were like, ‘hang on, what’s that one?’”

A Sheffield mum says she has footage of a ‘UFO’ flying over the Steel City - and even has proof it isn’t a plane.

Jennifer Dunstan says she and her cousin, Denver, were already watching the skies at around 6pm on May 6 when the mysterious white shape went streaking by. She said: “We were already watching this one plane, and Denver was using this app on his phone - it lets you look at a plane through your camera and it will tell you where it’s come from.

“Then we saw this other thing - and we were like, ‘hang on, what’s that one?’ I thought it was a plane of course, but when we looked at it through the app there was no result, as if it wasn’t a plane.

“The other plane had one of those little streams going behind it like planes do, but this other thing didn’t.”

The airborne object - which you can see in the video above - appears white horizontal and vaguely cylindrical while moving at high speeds across the screen.
