The first in a series of bonus episodes related to the theme of assassins will drop on Wednesday, September 13. To tide you over until then, I'm pleased to present two episodes of the History Daily podcast. History Daily generously featured an episode of The Art of Crime a few weeks back, so I wanted to return the favor. This episode is about the mystery of D.B. Cooper. On November 24, 1971, an unidentified criminal known by that name hijacks a Boeing 727, extorts $200,000 in ransom money, and parachutes to an uncertain fate.
