The latest episode of the “From Balloons to Drones” podcast is out now! This time we interview esteemed aviation historian Kenneth P. Werrell.

Werrell takes us through his latest book, Air Force Disappointments, Mistakes, and Failures, to tell us about aircraft designs that never took off. From those that were cancelled before going into production, or those that simply didn’t perform as well as imagined, some of the aircraft on the list might be surprising. All of them have fascinating stories.

You can listen to the show on Soundcloud, Spotify, or wherever you find your podcasts.
