All this speculation is not helping.
It’s what happens when an announcement of this kind isn’t conclusively detailed. And I say this with all due respect to Jay who may be constrained or reluctant to give a conclusively detailed account. Harmy has used TN1 footage in his reconstructions, other people have used Harmy’s reconstructions as the basis of shots in their edits. Unless people know in detail what happened they will speculate if only out of anxiety over their own projects or position in the edit/preservation community.
