I was not disappointed when I found out the PV doesn't have a microphone. Whirring props are hardly a compelling soundtrack. But what about this option? And it could be done with a software modification, no hardware needed: The ability to record audio into the mic on your iPhone? You could narrate your flight "Ok, this is 300 feet up. The tall building directly in front of me is the Bank of America building. This stream is usually only 4 inches deep. This parking lot is 800 feet long at this point." Etc. Etc. I would really like that feature. What do you think?
