A series of UFO sightings in Inverclyde were probed by the Ministry of Defence, according to newly-released documents.
Five separate incidents in the area were recorded between 1999 and late 2009 by a special Air Command department of the Armed Forces.
Entries included a report of two bright stationary lights hovering over Inverclyde and five lights over Greenock, both in 1999.
The files also revealed a woman saw a large bright light hovering in the sky above Kilmacolm in 2003 and a man spotted a yellow spacecraft above Greenock in 2005.
The most recent entry was on December 25, 2009, when two orange lights were seen hovering over Greenock.
The details were released after a request was made under the Freedom of Information Act.
A spokesperson for the MOD said: "The MOD has no opinion on the existence or otherwise of extra-terrestrial life.
"However, in over 50 years, no UFO report has revealed any evidence of a potential threat to the United Kingdom.
"The ongoing programme to release departmental files on UFO matters to the National Archive will continue."
