You can induce multiple Gs when pushing hard enough. Negative Gs and everything and everyone not strapped in flies into the ceiling. Which then must at some point come down.

Injuries from first crashing headfirst into the ceiling and then out of control falling back into your chair is a given when you have hundreds of passengers on board.

Especially on a Boeing which does not limit the flight envelope like an Airbus does.
