Ever heard of a G-force? When you make turn in a car, everybody seems to be pulled "outward" by inertia? same in a plane.

Not really Miko, because contrary to a car, the plane banks so your are more pushed on your seat rather than "lateraly". Bacause the car cannot bank and stays in the horizontal plan, then the centrigugal force pushes you toward the "outside turn door".
For the non pilots, you have to know two things:
(1) doors on C150/C152s are not with a latch that you turn 90 degrees like in the biggers Cessnas or pipers or airlines. With the age (not uncomon to fly Cessnas up to the 1960s) the door can be closed but opened by a shoulder bump.
(2) The use of the seat belt is mandatory by the pilot only. As a passenger, you legally should wear it in takeoff/landing/taxi phases. On top of the law, seen a lot of old timers, who after a lunch, don't fasten their belts for comfort.
Lastly, toejam happens. I remember forgetting to attach my seat belt for whatever reason as a flight instrcutor, going on a cross country and naping. I was laying by the door and the door opened.

Heart pumping wake up hehehe.
9,000ft? Dammmm that's a loooooooong climb to practice steep turns.
