The 60th anniversary of the ending of the West Berlin blockade by Soviet leader Joseph Stalin is being celebrated in Berlin. The BBC reports, and has a neat video.
In 1948, Stalin cut off all land links into West Berlin in an attempt to force out British, French and US troops.
Instead, the Western nations launched the biggest airlift in history to keep 2.25 million residents from starving.
For the next 11 months, planes landed every two minutes, bringing in total more than 2.5m tonnes of supplies.
Seventy-eight aircrew died in plane crashes during the operation.
