what do aeronautical engineers know that other people don't know? I can give you some few things that only aeronautical engineers know Why do airplanes have curved wing tips? During a flight, the pressure is lower on top of the wing than it is under the wing. The air tends to move from the high pressure below the wing to the low pressure above the wing around the wingtips. In the past, wingtips were straight, and the airflow caused severe turbulence. So aeronautical engineers decided to bend the wingtips upward to reduce turbulence, prolong the wings’ durability, and save a lot of fuel during travel. Thanks to this feature, we feel more comfortable during a flight. 2. Why do planes have different nose shapes? The nose of military aircraft is pointed. The sharper the nose is, the faster an aircraft is. But a longer nose keeps pilots from seeing the runway properly, that’s why passenger jets have rounded noses. But Concorde aeronautical engineers solved this problem in the 60s. Th
