A flurry of UFO sightings (in the UK) have led to calls for the Ministry of Defence to launch an official inquiry.
UFO experts believe the incidents, which happened in Shropshire, south Wales and Worcestershire earlier this month, are "particularly significant" because they included observations made by the crew of a police helicopter and military personnel.
Corporal Mark Proctor told The Sun he witnessed a "fleet" of objects objects zig-zagging across the sky at about 11pm.
The 38-year-old soldier, a member of the 1st Battalion Irish Regiment, said: "I was on duty in the guard room when the other boys outside began shouting.
"I went out to see what the commotion was about and could see 13 craft in the skies. They were like rotating cubes with multiple colours."
