"There i was..." is put out by the AOPA air safety institute and has live interviews with people who were in general aviation accidents or in incidence.

I also listen to "the finer points" with jason miller. He is a career cfi that goes through training scenarios and is a great resource for student pilots or people learning ifr.

Not aviation specific but "Well There's Your Problem" is a general podcast about engineering disasters with a few aviation-related episodes. For example: Episode 90: KAL Flight 007
