Seriously they just barely averted a major disaster here.

Looks like a big screw up by the AA 777 crossing instead of going down the parallel taxiway.

AV Herald comments suggest DL requires crew to be removed from flying immediately after a high speed RTO.

Why they didn’t have a backup crew is a good question but probably a sensible policy, the crew barely averted a disaster, makes sense to remove them from duty, I’m sure they had shaky nerves after the incident even though they weren’t at fault.
