Neil DeGrasse Tyson admits you can’t see earth curvature at 128,000 feet
This is a video from my youtube channel of Neil DeGrasse Tyson admitting that earth curvature cannot be seen at 128,000 feet and also a clip from an air force video of an X-15 flying at 317,000 feet showing an eye level and flat horizon. So many people are lying on youtube and other sites saying that curvature can be seen at the beach, from a tall building, on a mountainside, from a plane and many other places.
