I know class and I know drunks. I even know drunks with class, and that woman although drunk, has no class. With 100% certainty, I would testify in court that the person climbing those stairs into the plane is more than a little tipsy. Not only that, but well practiced in the way of pretending to be in control. From the slow gait, the holding on tightly to hand rails, all the way to her forgetting that the stairs are no longer under her feet, or that there is no railing.
I agree. I’ve watched it twice and she is very unsteady on her feet. She also slows down noticeably about 3/4 of the way up the stairs, as though she either very weary, or wobbly, or both.
