Hello, I've had a budgie since Christmas 2017 and he's an enthusiastic flyer! He's allowed to fly around like crazy every day and he also flies back to his cage on his own. However, we bought a new bird today because he feels so lonely and he was quite shy at first and just spent…

An airplane flies due to lift because its wings are asymmetrically shaped. See https://de.wikipedia.org/wiki/Dynamischer_Auftrieb But how is it possible for an airplane to fly upside down? (see photo) Shouldn't the shape of the wings create negative lift that pulls the aircraft towards the ground?
Why are airplane wings curved? (Yes, I know it doesn't provide lift, but why?)
Are these 'single surface' wings?
Hello folks , I flew from Munich to Frankfurt today, at short notice, on what I assume is a Boeing 737-8, and I somehow had the feeling that the spoiler might be damaged. Is that normal or not? I took this picture on the plane.
Why is the wing profile of passenger aircraft asymmetric, but the wings of, for example, fighter jets or single-engine acrobatic aircraft are symmetrical? Yes, of course, a passenger aircraft is not designed to fly upside down, but if you can build symmetrical wing profiles for single-engine propeller aircraft, why not for commercial or larger aircraft?
What do you call the circled part on the piano in the picture? Is it called a track? Or what is it called? Please reply quickly!
