The Greatest Escapes

Some of history's greatest tales are stories of escape, the most incredible of which defy explanation. How did Harry Houdini pull off his daring feats? Was the "Escape from Alcatraz" in fact, successful? And what about the mysterious guidance one man received that allowed him to escape the South Tower of the World Trade Center on 9/11? Are there strange forces these escapees draw upon to beat the odds, where so many others fail? Or, like a great magic trick, will the secrets of how they cheated captivity remain UnXplained?
