The very thought of a non-qualified person issuing a MANDATORY stop call - at any speed, including above V1 - brings shivers to my spine
Whilst I dont disagree with you BOAC, I dont believe that was in the "spirit" in which the comment was intended

It also wasn't what was actually typed..nor was there anything to say 120.4 was conveying what was said verbatim.
You and I both know that Boeing have undertaken extensive studies of highspeed rejects above 80kts...and the corresponding findings. I would also hope that you are not suggesting that 3 sets of eyes are not at least as good as 2 sets, and that an ATCO although not qualified, is still a professional observer and perfectly capable of bringing an abnormality to the crews attention.
You also know full well that the commander makes the ultimate decision to stop or continue..so in that regard you've confused me with your comments
