As per the ground staff, VOTV had some low clouds on that day. My guess is, they never saw the runway till they busted the minimums on their 7th approach.
Calm winds, nice slow and stabilized?
Go to the minimums, take a good look, then take another good look:
Oops, here is the approach lights, here is the runway lights, and here is the runway. No drama, no 6 missed approaches, no minimum fuel and no emergency.
