Dropping a bouncing bomb Before being released from specially modified aircraft, the bombs were held by v-shaped arms in the plane and rotated to the speed of 500 rpm by a hydraulic motor and belt drive. The planes had to fly at the low height of 60 feet (20 meters) and to be travelling between 240-250 mph (400 km/h).
They were known as ‘bouncing bombs’ because they could skip on water and avoid torpedo nets, before sinking and becoming a depth charge. They had been tested in Watford and then on the disused Nant-y-Gro dam in Wales and at Chesil Beach in Dorset.
What did Barnes Wallis design?
Wallis was an engineer and inventor, most famous for developing the « bouncing bombs » used by 617 Squadron (« The Dam Busters ») to breach the M hne and Eder dams in Germany in 1943. He also designed the geodetic structure for the Wellington bomber (and other aircraft) and designed the successful R. 100 airship.

How many Dambusters came back?
At the final briefing late on the Sunday afternoon, Wallis had addressed 19 crews. The next day, only 11 of them came back. Fifty-six of the faces into which he had looked justa few hours before were gone, and all but three of them were dead.
How did the Lancaster bomber get its name?
The Avro 691 Lancastrian was a Canadian and British passenger and mail transport aircraft of the 1940s and 1950s developed from the Avro Lancaster heavy bomber. The Lancaster was named after Lancaster, Lancashire; a Lancastrian is an inhabitant of Lancashire.
Where was the bouncing bomb designed?
A breakthrough in the back garden In 1942 British engineer Barnes Wallis began working on plans for a bomb that could skip across water. He developed the idea by experimenting with bouncing marbles across a water tub in his back garden.
How many of the Dambusters survived?
Eighty men survived the raid. Of these, 22 were killed serving in 617 Squadron later in the war and 10 more were killed while serving with other squadrons. Only 48 men who took part in the raid survived the war.

How many planes returned from the Dambusters raid?
The attack had huge propaganda value and made Gibson a national hero. Of the nineteen Lancasters that took part in the attacks with 133 crew, eight planes were lost with the loss of 56 men; three of these men survived to become prisoners-of-war.
Where were the Dambusters based?
RAF Scampton
Where was the bouncing bomb invented?

Was the bouncing bomb a success?
The raid did succeed in breaching two dams, causing considerable chaos and loss of life. But Professor Morris asks if Operation Chastise – as it was codenamed – was truly successful. “It is not as if Chastise succeeded on its own terms,” he writes.
Where was the bouncing bomb dropped?
Chesil Beach
