In 1983, a plane takes off from Ottawa with less than half the required fuel on board. As the engines cut out one by one, the pilot is left with a ticking clock and an impossible task. But what does a tale of an unusual plane crash have in common with one about a disappearing canal?

For this special episode, Tim is joined by colleagues from across Pushkin's podcast network. Heavyweight's Jonathan Goldstein stops by to muse on the cost of mistakes and whether we're really in control of how many we make. Plus, Nate Silver and Maria Konnikova from the podcast Risky Business give a gambler's take on the strange science of regret.
