There are people from home and abroad attending the official opening of the International Bomber Command Centre near Lincoln today.
The centre (above) aims to ensure the 53,000 members of Bomber Command continue to be remembered.
One of those at the event today is Coby Van Reil, from the Netherlands (below).
She says crews from Bomber Command saved her life.
In the final days of the war they stopped dropping bombs and instead dropped food parcels over her home city of The Hague.
The effort - called Operation Manna - meant the starving population, who had been cut off by the conflict, could eat and survive until more help arrived.
