Podcast:Cautionary Tales with Tim Harford Published On: Fri Sep 04 2026 Description: Evel Knievel, the world-famous daredevil, is planning his greatest ever stunt. In 1974, he wants to leap over Snake River Canyon in Idaho. The chasm is almost a third of a mile wide, much bigger than any jump he's done before. To make it work, he'll need a custom-made rocket-powered "Skycycle," TV camera crews and - most importantly - a very positive attitude. For a list of sources, see the show notes at timharford.com.
