I'd say by observing the first example in the clip, it seems very realistic how she reacted as a student of the Wing Chun sciences. I am only referring to her second nature timing based on a lot of training and conditioning. Wing Chun teaches and conditions a lot of sensitivity and "feeeel", plus the fact often in Wing Chun we are taught to learn to relax in such sudden situations. When you first comply with your attacker and remain calm, it creates the ATTACKER to feel less edgy and slightly underestimate you. If you tense up however and start to struggle, this makes the attacker more nervous and desperate to control you. I think the lady air flight attendant had the advantage of sudden "art of surprise/shock" on the attacker thanks in part to her being calm and not tense or struggling against him.
I am not too sure of the results though. I'm having a good hunch she in real life would have been cut at least once. Dealing with a knife wielding attacker is not as what it seems like in most of these videos. Using a knife as a weapon to attack someone is very very effective and deadly. If O.J Simpson (assuming he was guilty lol
) didn't have those two knives and was empty handed, chances are his wife and Ronald Goldman would still be alive today.
If prisoners in the prison yards and showers used less "shanks" or ice picks, there would be less murders in jail.
Even the most unskilled person can yield a knife and really injure or even possibly kill a very skilled fighter.
So this video clip to me merely demonstrates and practices a principle or guideline, I don't think the whole thing is written in stone. Just something to consider and even learn some perspectives from.
