Guest: Dr. George Nield, Associate Administrator for the FAA Office of Commercial Spaceflight, was the guest for this program. Please note that there is audio noise on this recording coming from the hotel phone line. I apologize that a better quality connection was not available. We began our discussion with a tribute to Apollo 11 landing on the Moon given today being July 20. Dr. Nield gave us a good overview and comparison of the evolution of aviation as compared to the evolution of spaceflight. You will not want to miss this part of our discussion.
