A Bomber Command veteran left his medals at a service station en route to the unveiling of a new memorial to those who served in the squadrons.
The 30-metre high Bomber Command memorial spire was unveiled in Lincoln on Friday and displays the names of tens of thousands of air crew who died protecting the country.
The International Bomber Command Centre sent a message out on Facebook asking for help in tracking down the veteran's medals.
The message said: "A Bomber Command veteran has lost his medals at a service station on his way to the Memorial, somewhere near Newark, possibly Spital services.
"Please like and share and hope we can get them back to him safely."
