Has anyone actually verified the date of the video?
If it was windy and the crew applied Boeing’s winshear technique they can delay rotation to calculated Vr+20, or Vr equivalent to RTOW whichever is lower. This is to account for wind shear encounters on rotation.
The “latest 2000’ before runway end” applies to wind shear encountered during the takeoff roll.
How do we know this isn’t what the crew were doing on this day? BTW I’m not a RYR apologist before someone mentions that.
