June 30, 2026 - Crossing the Impossible

Tuesday, June 30th, 2026 — Today is National Handshake Day, and today's stories are all about people willing to take extraordinary risks.In this episode, we follow Charles Blondin as he becomes the first person to walk across Niagara Falls on a tightrope... investigate the mysterious Tunguska Event that flattened millions of trees without leaving an impact crater... and celebrate the birth of the Chevrolet Corvette, just one day after saying goodbye to Pontiac.Plus, a birthday tribute to Vincent D'Onofrio, one of Hollywood's greatest character actors, whose remarkable ability to disappear into a role has made him unforgettable in everything from Full Metal Jacket to Daredevil.Some risks change a life.Others change history.Anyway… that's what I ended up finding while working through June 30.
