A UFO was spotted darting across the night sky above a garden in Wakefield.
The mysterious triangular 20ft long object was described as “shiny and grey” by a resident who reported it to the Ministry of Defence (MoD).
The close encounter was one of a string of freshly declassified UFO sightings and MoD files released by the National Archives Service yesterday.
A city resident, whose name and address has been omitted, sent a letter to the MoD on August 8, 2007.
They said: “The object was an elongated, triangular shape with rounded corners and a sort of satin finish, charcoal grey colour.
“I would estimate the object to be around 15ft across and 20ft long. It was absolutely silent, very low in the sky and moving quite fast.”
A response from the MoD, sent less than a week later, said it had no reports of any breach of airspace that night.
