      I might consider this, however seriously if I'm paying I want my private data not shared with anyone and well protected. If curiosity then makes me agree to the following terms:
      - to the cross-border transfer of my personal information to countries that I understand may not have the same data protection laws as my country of residence.

      Then my initial thoughts are, okay so I'm paying but you might still use my data for data mining? Then why the hell am I paying?
      Am sorry to say this but either your model is data mining and you make your stuff free (YT, FB do this), or you make it a paid subscription and you don't show me ads and don't mine my data.

          Please correct me if i'm wrong but a pilot told me that high mounted wings do make planes stable in a way similar to the pendulum effect. ''keel effect'' . It IS (also) the drag vertical component of wing drag that acts as a parachute. It is not the lift's vertical component as that is perpendicular to the wings surface (not to gravity) so not upwards (inverted pendulum fallacy).

                    Yooo you gotta do an episode for SNC’s new Dream Chaser space plane. And another for Virgin Galactic’s new passenger space ventures. Blanking on the name rn but it’s basically a triple fuselage with two airplanes in one. Looks like a lot of state of the art engineering and cutting edge techniques went in to these crafts and I’d love to see you break down the physics of it all!!

                      a tad bit disappointed, didn't satisfy many that question the anhedral wings applied in Tupolev airliners ranging from Tu-104, -114, -124, -134, up to Tu-154

                                            Unrelated question: Why don't we use nuclear power for space travel? Not that I support Nuclear power in any way...but why hasn't it been tried before? Too expensive? Not efficient? Too dangerous?

                                              Nuclear power is just too powerful. The concept was explored several decades ago where small atom bombs would explode underneath a push plate, connected to the spacecraft via a dampening mechanism.
                                              The main advantage is that the craft could, and had to be quite heavy (in order to accelerate at a tolerable rate).
                                              The main problem was that each blast would remove a certain amount of material from the push-plate. We still don't have any material which can survive the amount of blasts needed.

                                              Even the smallest nuclear bombs are simply too powerful. If one day we can control fission or fusion, a few atoms at a time, nuclear may well be a solution.

                                                    Cargo planes typically have high mounted wings so the loading deck is closer to the ground. Vehicles can drive on instead of being lifted up.

                                                      As a former C-17 loadmaster the rational for the top mounted wings, as it was originally taught to me, is indeed to get the body of the aircraft as close to the ground as practical. This is primarily done for the last reason stated 4:49, to ease on and off loading. Most vehicles enter a military cargo planes under their own power, so having a cargo ramp with as shallow an angle as possible is required.

                                                            It is not a greater angle of attack (AOA) that makes greater lift on the lower wing. AOA does not change when an aircraft rolls. It is the greater vertical component of lift that is created on the lower wing (with normal dihedral) when the aircraft is in a bank...
                                                            Just saying. Mostly right, but that part is incorrect.
