I also looked at huge search results and cannot find any photos with any gap between object and plume.
I also cannot find any video of more than a few seconds duration.
I cannot find the original video, or even an uninterrupted one or two minute segment.
I thought about measuring the largest piece of perhaps 4 seconds and then extrapolate from that as to total launch and boost time recorded but this would be wild guesses. Others, bewilderingly, believe they can measure and prove, direction and speed and height and much more but we have NO information at all and so we cannot: even distance this began offshore is not known- could be much less or much more than 35 miles.
I cannot even find definitively what is the first raw frame taken.
You do remember those pics don't you? I saw them posted several times here.
I cannot find the original video,...
I don't know what you mean by "original?" If you mean the full 10 minutes that one CBS reporter said Gil filmed I don't think the public has ever seen that. A pox on CBS for not releasing it. If you mean what CBS LA originally aired I think that's here. Raw video - CBS LA Second video down. If it starts with the interview you didn't scroll down enough. If a longer video was ever released I don't think I have seen it.
