I shared this with a recently-retired tower agent/ramp controller whose best guesstimate was that the footage, at least of Delta operations in A Tower, was taken a couple of years ago. It's pre-COVID (no masks), a different tower agent/operations facility has since opened and some of the folks seen on the footage haven't been in that role for a while. Though it's not the same as previous videos that have been shared here, the featured people/commenters are different.

Still fun to watch!
