and were in CAVOK weather conditions
Several aircraft have inadvertently been flown into the ground in Antarctica in CAVOK conditions....
SKC however is a different story. That's, as I am sure you are aware, one of the traps of whiteout and that until you have seen it for real is just so hard to imagine for most out of a textbook.
I once had an experienced met forecaster on her first ice deployment on board and brought her up to the flight deck to show her whiteout under a thin 6000 agl altostratus deck over the plateau. She was speechless.
