Horncastle’s very own Dambusters hero George ‘Johnny’ Johnson is featured in a new photographic tribute to the legendary mission.
Mr Johnson, who was born and raised in Hameringham, is one of only three survivors from a bombing raid on German dams that helped turn the tide of the Second World War.
To help commemorate the 70th anniversary of the raid, researchers at the BBC have tracked down images of all 133 airmen from 617 Squadron who took part in the mission - including Mr Johnson.
Now 91, Mr Johnson lives near his family in Bristol.
He returned to Woodhall Spa earlier this year to take a prominent role in the anniversary celebrations.
Woodhall Spa has strong links with 617 Squadron and there are two memorials in Royal Square.
The Officer’s Mess moved to the Petwood Hotel after the Dambusters mission, which was launched from RAF Scampton.
Several other important raids took place from Woodhall Spa.
The Dambusters enjoyed greater prominence after a 1955 film highlighted the exploits of squadron leader Guy Gibson and his heroic crews.
The raid - on May 17, 1943 - involved 19 Lancaster bombers. Eight aircraft failed to return. More than 53 crew members died and three were captured.
Mr Johnson was a bomb aimer on a Lancaster that attacked the Scorpe Dam.
Speaking at the anniversary earlier this year, he said he would never forget the mission.
He added: “I am very proud to have taken part. I was one of the lucky ones. A lot of good men, brave men, lost their lives.”
The 617 Squadron will hold a reunion in Woodhall Spa in November.
