I'm still disappointed that Brad Bird didn't explore Helen's fighter pilot background in the 2nd film.
That back story for Helen was created when Brad Bird axed a side character that appeared for the plane scene then was instantly killed off at the end of the missiles one scene later.
What resulted was one of the most intense scenes in animation to that date as you watch Helen switch back and forth between her ex-fighter pilot self dodging missiles in a passenger jet and her as a mother encouraging her daughter to have enough self-confidence to make a force field big enough to protect the plane.
I want to see what Helen was like behind the stick of a proper fighter aircraft, I want to see how she learnt those skills.
