A couple of years ago when I first got an iPhone I downloaded from
iTunes and listened to an aviation podcast. I was not impressed as the speakers were amateur enthusiasts who were clearly not that well informed.
I then started listening to
EconTalk, a series of excellent podcasts by economist Russ Roberts from GMU in Virginia (he also blogs at
Cafe Hayek). Each week he interviews at length a distinguished economist in a manner that is not overly technical.
For lighter relief I have been listening to the
Friday Night Comedy from BBC Radio 4. These generally take the form of a quiz or short monologues focussed on the latest political news from the UK.
More recently, I have been listening to a couple of much more professionally done aviation podcasts.
They have turned out to be excellent with coverage of civil and miltary aviation, including aviation history and technology. I have been listening to older episodes and have even sent off a couple of possible "Grill the Geeks" questions to the USA.
These have all been great listening while walking our two dogs.
