French acrobat Philippe Petit performed a high-rise act between the twin towers in New York City on this date in 1974.

Petit and his team climbed to the top of the World Trade Center in 1974 to perform a feat documented in 2008 feature, Man on Wire.

Petit crossed the span several times without a net, laid down at times and scampered back and forth for around an hour before coming off and into the hands of the New York City police.

Here's the archive footage from CBS.
