KEY POINTS:
New Zealander Les Munro - the last surviving pilot from the famous British "Dambusters" bombing raid - is among a few invited guests to witness the flight of one of the last two airworthy Lancaster bombers to mark the 65th anniversary of the raid on May 15.
Mr Munro, 89, of Tauranga, flew one of only 11 planes to return from the raid in 1943.
His Lancaster, W-Willie, was damaged by flak over Holland and turned back to England still carrying its bomb, but the New Zealander went on to win the Distinguished Service Order and Distinguished Flying Cross and reach the rank of squadron leader.
"It's a great feeling to be able to come back and meet comrades from that time," Mr Munro told the BBC.
