If you have a boeing 737 flying at 35000 feet at 500 mph then there will be a higher pressure on the front-facing cockpit windows due to the air coming at it at 500 mph and being deflected up and to the side.

However the air pressure at altitude is itself a third of the pressure at ground level and certainly less than that inside the pressurised cabin.

So if you could open the front window, would air rush in, or out.

Are there any modes of flight where the two are equal?
