How One Engineer’s “Crazy” Modification Made Tanks Nearly Unstoppable

In 1941, a Hungarian engineer convinced generals that tanks could swim. With canvas curtains. Everyone thought it was crazy. Until D-Day proved it worked.
Full Description (1,800 characters):
Nicholas Straussler had a seemingly insane idea: to float 30-ton tanks using canvas curtains. No giant floats. No special boats. Just waterproof fabric and simple physics.
When he presented the idea in 1940, engineers laughed. Generals shook their heads. It was impossible. Tanks sink. That's common sense.
But Nicholas didn't give up. In June 1941, in a secret lake in London, he proved the impossible. An obsolete tank floated. It sailed across the water. It worked.
Three years later, June 6, 1944—D-Day. Hundreds of tanks equipped with Straussler's DD (Duplex Drive) system swam across the English Channel under German fire. On some beaches, they saved thousands of lives. On others, poor conditions caused tragedy.

This is the story of unconventional innovation that changed warfare. Of persistence against universal skepticism. Of simple genius solving impossible problems.
Nicholas Straussler never became famous. But his swimming tanks crossed the English Channel. And that changed everything.
