The snag with barreling down the runway in extremely low vis is the dreaded RTO at or near V1.
It's ok for the aircraft with virtually centre-line thrust (e.g. VC-10 or pretty much any fast-jet), but once you're talking about aircraft with pods on the wings... well.... it would take a crew with bigger beachballs than I've got !
Almost guaranteed to come hurtling off the side of the runway. Erk. But back then men were men and guys used to fly Canberras home at the weekend
Sometimes a tricky consideration - do you de-rate and spend longer on the runway, or ramp up the thrust and have a bigger assymetric problem if one does die on you...
