Be Amazed at… The mysterious triangle symbol over your seat – When you board a modern jet aircraft, you’re probably looking for your seat number and for the nearest emergency exit. The flange sticking out of the wing – While you’re waiting to leave the gate, you’re probably staring out the window at the wings that are going to carry you off this Earth. The hum when you board the plane – Have you noticed that there’s an omnipresent drone while you’re waiting for the last passenger to board the plane? Tomato juice – Do you find yourself ordering a tomato juice when you’re on a plane? Opening window shades for landings and take-offs – I bet you thought the window shades were installed on planes so you can sleep during long flights. Winglets – Airplanes are always a tug-of-war between the thrust of the engines and aerodynamic drag. Sidestick – Back in the day of the first planes, pilots were known as “stick and rudder men”, steering the plane by the power of their arms and legs pushing on control cables. Bleed air system – While the Wright Brothers’ Flyer barely flew above the dunes at Kittyhawk, today jetliners fly higher than the tallest mountains. The eye level indicator on cockpit window – Pilots come in all sizes – and just like your car, planes have adjustable seats for them. The hole in your window – Since cabin pressure is so important, you might not think a hole in your window is a good thing.
