In the first video, it's just the beginning of lift-off across the Indian River. Please note that there are many voices in the background - only 2 of them Hub's and mine. So if it's dorky, assume we didn't say it. K? Thanks. :)
Note in this second video that you can hear the crackle of the shuttle. In this particular spot, you don't hear the sound as well as you do in others out there, but the crackle is audible. It's similar in my mind to the crackly whistle of a propane torch. Also note that there is a renewed cheer at an odd time. Apparently that's because tradition dictates that it's polite to cheer after waiting 45 seconds, as the crew is most likely in the clear after that time. We could even see the booster separation very clearly! The sun glinted off them just the right way so that we could track their entire progress as they fell. I've heard that you could even see them in central Florida about an hour away.
