The bizarre black ring-shaped UFO was filmed floating above the M62 near Birkenshaw (right). It is the latest in a string of strange sightings with one filmed floating over Disneyland in California just last year (bottom left). In 2015 eerie footage emerged of a 320 feet-wide (100 metre-wide) ring of smoke floating over clear skies in Kazakhstan (top left). But one expert has revealed the latest black ring was simply the byproduct of cannon fire of a battle reenactment at the nearby Yorkshire Wartime Event.
