Crank out frameless windows question

If they have latches, the windows should not open no matter what the wind pressures. If just cranks holding them closed, it would be unusual for any expected wind pressure (i.e. highway speeds) to pull them open against a worm and sector mechanism if they have been closed tightly against the gaskets in their frames (frameless windows have frames, the glass just hides the frame).

Luggage doors should not open if fully latched. The problem with some of the latching mechanisms is that you can lock them even if the latches did not engage.
