While Walter Cronkite and Jules Bergman were the definitive space program authorities of the halcyon days of NASA in the 1960s, WMFE's Pat Duggins is radio's current space expert. That's reason enough to listen. The program blends historical material (audio from the Challenger and Columbia disasters, historical recollections) with current interviews and analysis; the interview with the sister of Discovery's commander is especially interesting.

Hearing the audio from both the Challenger and Columbia disasters was especially chilling, because I - probably like most space enthusiasts - still remember where we were in 1986 and again in 2003.

This documentary would make a good "Sunday evening" program, when listeners aren't distracted by a zillion other activities.
