Today's program was OPEN LINES and extended beyond the two hour time due to a last minute 11th hour listener phone call. In segment one, I read a series of questions from listener Kelly that came in by email and we made those discussion topics, focusing on the viability of commercial space and comparing them to civil space programs.
