Do we, Flat Earthers, know why Globies have to act dumb when confronted with something they can't explain with logic?
No, you, a particular Flat Earther, is yet again suffering from what's known as "YouTube Search Results Cognitive Dissonance Syndrome".
Logic Explained:
Rocket #1: mak3m explained.
Rocket #2: I have no idea what that is supposed be trying to show, but it is showing nothing.
Rocket #3 in your video. It's moving at 2000 m/s. If it hit something at that speed, anything, be it a hard or magically suspended water dome, it would disintegrate on impact. It doesn't. In the video, the original footage at mark 2:01, it says "YoYo Despin". Through the wonders of modern rocketry and Yo-Yo physics, the despin mechanism, outstretched cables with weights attached, are deployed counteracting the spin of the rocket, hence YoYo Despin. Look it up.
Same for rocket #4 in the video. This same footage was used by an FEr where he too thought it hit a dome. He realized it didn't. Here's his follow-up to his original video he made explaining that he was wrong. As are you:
Rocket #5: More nonsense. See #1
Rocket #6: Goodness, the nonsense keeps piling on, see #5 & #1.
Rocket 7#: Looks like a failed launch.
