AvFacts is a podcast by Tim Morgan that introduces you to a new aviation topic
with each episode. I’ll walk you through interesting topics covering aircraft
big and small, civilian and military, airplanes and helicopters, and
everything in between. As long as it’s interesting and has to do with
aviation, I’ll talk about it on AvFacts.
