I am with '18 - Wheeler' regarding this, in more ways than one!
Just an additional point, regarding auto-brake operation, at least on the B747 Classics, but I'm sure the 'other one' also has this, it's quite logical, really!
With "MAX" breaking selected, initially you will only get "MED" braking with wheel spin-up, with "MAX" being conditional on the nose gear (squat switches) detecting the NLG is on the ground.
Pity the -438 that went for a "hole-in-one" attempt, didn't have an FE to wake the Captain up to what was actually happening, maybe, just maybe, then that would not have happened!!
Cheers
