1-The mysterious triangle symbol over your seat; it comes in red or black and are used to indicate the best vantage points and the window under the sticker provides a good view.
2-The flange sticking out of the wing is a part of the evacuation system. If the plane is forced to land somewhere that you can’t use stairs or terminal boarding bridge, you will have to exit through the over wing using the guide ropes tied around these flanges.
3-The humming sound when you board the plane is the sound of the auxiliary power unit[APU] which provides electricity to the plane temporarily until the plane is ready to take off.
4-Tomato juice is suggested to have instead of other food because the sweetness of the taste buds reduces while flying high and the sense of smell is decreased.
5-The isty bitsy hole in the bottom of your airplane window is actually a very important safety feature. It is called a breather hole and is used to regulate the amount of pressure that passes between the window’s inner and outer panes.
