Latetonight, yea mate about as irrelevant as saying it's 13,000', point is this is where following the GS puts you, what air distance the md-11 uses from the threshold I don't know, especially since they had a CAS of about 170kts you assume they crossed the threshold at 50'.
The third touchdown where it breaks is between 2,500 & 3,000' with a CAS of 150kts, where does that fit in your 50'?
