A UFO spotter is appealing to fellow sky-gazers to solve a mysterious sighting of spherical objects on the horizon.
Andrew Burlington, 40, was on a family outing with his parents and young nephews when he saw what he believes could have been a fleet of UFOs.
The computer technician said: “We thought the objects were balloons at first because they were spherical and some had small objects hanging from them.
“But they were soon out of sight and the last object in the fleet appeared to lose altitude and flash a few times before slowly turning invisible.
“The fact that a long anomalous object shoots across the sky at the start of the video may well indicate that a UFO mothership was above the Thames Barrier releasing smaller UFOs.”
