I have. Saw it happen, again, just last month, with an OW student during Confined Water Dive One. I won't even say she 'put it' on her forehead. Rather, she pushed it up off her face.Who has ever for real seen a panicked diver put their mask on their forehead? Not read about it, but seem it.
Not at all.The whole concept seems ludicrous to me, if they are panicking surely they'd rip it off completely.
In fairness, I don't know that the diver last month was truly panicked. She was DEFINITELY very anxious / stressed. Part of the same continuum, though. Pushing the mask up on the forehead may not be the one, and only one, universal reaction. But, it is certainly one reaction to stress / fear / panic.
