“I didn’t go THAT far back-I think the link brought me in after that admonition. I tried going back, but just couldn’t navigate to the correct area in the video. Thanks for that info.”
You’re welcome. This is a good starting point, which shows the DEI plane approaching to land. You’ll then see the Delta plane starting to take off, then the tower tells the DEI to not cross the left runway (as it’s slowing down after landing), and the DEI pilot reads it back correctly. Then if you look carefully (very carefully), you’ll see the DEI plane plane go over some runway markings, which is when the tower yells: “Stop! Stop! Stop!”
