Korean pilots are trained differently than most pilots. But did that hands off approach cause the crash that left two people dead?

KFBK'S  Tom Sullivan is a pilot who has flown in and out of San Francisco a number of times. Sullivan said if Saturday's crash was caused by pilot error, it may be because of the training Korean pilots get.

"In most planes, most airlines, if I see something you're doing wrong, I say something. But in the Korean culture, it was inappropriate to do that, and so they never said anything to the captain, even though the captain was making a mistake -- that's the idea of crew resource management..."

He says if the pilot-in-training was too low upon approach, another pilot should have told him, and he should have made the adjustment.
