Flying is truly remarkable. Many people get their experience of flying from being a passenger in a commercial aircraft. For others their experience is doing the actual flying and being a pilot lets you really understand what flying is like.
As a passenger in a commercial aircraft you don't get to experience too much. Sit back, look out the window and maybe you'll feel a little bit of g forces every once in a while; plus turbulence, lol there will always be turbulence. Now if you were a private pilot flying your own aircraft you could do so much more that would get you arrested so quick or potentially killed if you were to attempt in a commercial plane. That's why I don't think of commercial flight as a real flying experience, unless you're flying in the mountains of Indonesia or Malaysia.
Being a private pilot with a sports rating and sport plane you can do many things. Some maneuvers are barrel rolls, inverted flight, loops, stalls and going negative g's. I personally was able to pull negative g's and positive g's but I prefer zero g's. G stands for gravity. Anytime that you're not accelerating you will be at 1 g which is just your normal weight. At zero g's then everything experiencing it will be weightless, anything higher than 1 g will be heavier.
I have also experienced stalls and preformed a stall a couple times during a flight. I was nervous but also really excited. So after take off my orientation pilot let me take the controls and gave me a heading and altitude to fly, when we got to altitude I gave the pilot back the controls. We were discussing why and how aircraft stall prior to me returning the controls because it's a learning flight. So as we discussed, he lowered the throttle and kept the same angle of attack; our airspeed started to drop. I could see that he had to constantly pull the controls back slowly (pull up), and when he couldn't pull anymore a few seconds later while still losing airspeed the alarm went off, lots of vibrations, and then a sudden nose drop free fall. I felt nervous when I saw the nose of the plane pointed strait down. The pilot waited about 3 seconds so i can fully experience the stall then went full throttle, picked up speed, and then pulled up to level the wings to the horizon.
Stalls happen when an aircraft has too much angle of attack or to dumb it down, not enough airspeed for the angle the plane is flying at, so the plane drops. Stalls aren't hard to recover from unless you don't have any engine power. They must be avoided at low altitude or the plane could crash because you lose altitude really quick. That's why take offs and landings are crucial times for a plane because that's when the aircraft is at low altitude and low airspeed. Take offs are not as stressful as landings because the airspeed and altitude are increasing but if engine power is lost then things can get worse than just a lost engine.
