And it's 80 years since the Dambusters raid, one of the most daring attacks on Germany by the British in World War II.

In 2013, I spoke to George Johnny Johnson, who was on the mission.

It's May the 17th, 1943, a news comes through of a spectacular raid by the Royal Air Force in Germany's Rua Valley.

This is London. The Air Ministry have just issued the following communication.

In the early hours of this morning, a force of Lancaster's of bomber command led by Wing Commander GP Gibson, DSO-DFC, attacked with mines, the dams of the Murna and Sova reservoir.

The targets were the strategically vital Murna and Zorba dams, which supplied water and electricity to Hitler's main arms factories.

Former bomb Aimer Johnny Johnson was in a group of planes which raced at low level towards the Zorba dam, semi-hidden in a steep valley.

It was absolutely exhilarating. I'm flying lying down. Most comfortable, positioned in the aircraft with cushions to lie on.

Just watching the ground whizzing past underneath you, wonderful experience it really was.

I've relatively difficulty finding the Zorba to start with, mistressly getting into thinking about quite a bit.

We eventually found it, and for some reason, the dam itself was in brilliant moonlight, absolutely clear.

We were supposed to fly, as I said, with the port out your engine over the dam, aimed to release the bomb as near as possible to the centre.

Not easy, positioned to get into. If I wasn't satisfied, I could dummy around.

And I discovered how to become the most unpopular member of crew in double quick time.
