Damage assessment, source and supply possibly 12 new wheels, transport to Korea, ( 6 hours), and fix, 19 hours sounds fair to me, what is your gripe Geebz?
Just towing the A/C back, cooling brakes, deboarding, unloading etc could take some time. If more fuel uplift or even worse, defuelling before replacing tires was needed, the delay sounds fair to me as well.
As a pilot, if the ATC tells me to stop immediately, I can count on the reason being a runway incursion.
With speeds of up to 300 feet per second, a p1ss1ng contest of who's in charge would be the last thing on my mind
