She's in shock.

I'd agree with you but she is composed enough to film the whole thing.

Some people are totally cool when crap hits the fan and don't freak out at all. Training and experience helps but it's not odd for someone to be able to pull it off naturally (see "bystander does something heroic" type stories).

x2 on the shock and fear thing as well.
