well, I think that it a topic for a conversation, I do understand that in normal operation you should not open the window during a flight, but for me it a standard test to test the quality of the addon, physically it should not be possible to open the window during the flight due to the compressed air inside the airplane pressing the window to the frame, so I'm testing it on each airplane I'm flying, you won't be able to open the window on another company, maddog, QW146, even on the tu-134 also you have make it impossible to open the window on you's 757/767 during the flight, I found a lot of similarities to your 732 and it make me think that a lot of elements based on the 732 where you can open the window during a flight, as a new addon I think that it will take this addon one step forward instead of benign a modification of the 732
