The image shows a close-up of a white door with a round window in the center. The window has a red arrow pointing to the right, indicating that the door is closed. Below the window, there is a red text that reads "DANGER: DO NOT OPEN DOOR. IF RED WARNING LIGHT IS FLASHING (Cabin PRESSURIZED)". The text is written in black and is clearly visible. The door appears to be in a room with a gray wall in the background.
