The Highballs were the anti-ship version of the cylindrical Upkeep bouncing bombs
used by the RAF in the Dambusters raid in May 1943, both having been designed by Sir Barnes Wallis to bounce over water.
Highballs were the anti-ship version of the more famous cylindrical 'Upkeep' bouncing bombs
used by the RAF in the famous Dam Busters mission of May 1943.
FACTFILE BARNES Wallis produced various prototype bouncing bombs
Conventional bombing of the time was not accurate enough to destroy so small a target as the dams, so Wallis, an aeronautical engineer, developed a theory for a bouncing bomb
It turned out to be the perfect way for Mr Wallis to investigate how his bouncing bombs
idea could work in reality.
The raid is, of course, synonymous with the use of the specially developed bouncing bombs
, codenamed Upkeep, invented by Barnes Wallis, which were designed to be dropped from a low altitude and skim along the From 19 surface of the water into the dams.
The classic film, about the crack team of pilots and engineers who use revolutionary bouncing bombs
to destroy a vital Nazi dam, is based on one of the most glorious - and tragic - events of World War II.
Inventor Barnes Wallis used his daughter's marbles and a tin bath filled with water to design the bouncing bombs
used in the attack.
Dambusters:Building the Bouncing Bomb
(C4, 8pm) Cambridge lecturer Dr Hugh Hunt is an expert on rotating objects, and in this documentary he takes on the task of trying to recreate the raid on the dams of the Ruhr valley.
The mission was branded a success and immortalised in the 1955 movie, which starred Michael Redgrave as engineer Barnes Wallis - creator of the bouncing bomb
- and D-Day veteran Richard Todd as Wing Commander Guy Gibson.
Barnes Wallis believed a bouncing bomb
that would clear protective nets, smash into the dam wall then sink to 30 feet and explode would break the dam.
THE designer of the bouncing bomb
used in the Second World War Dambusters raid was remembered yesterday in a flypast on the mission's 60th anniversary.
