>>12892011Hitting a domed ceiling wouldn't cause the spinning to slow like that, and the sound would be more of a "WHAM" instead of a "VVURR".
Also, if it hit a ceiling, why is the rocket still pointed straight upwards after the supposed impact?
I'm not a rocket designer, but I think the sound was probably from reaction wheels to make the rocket stop rotating.
Pic related appeared after the supposed impact as well. Could it be from some kind of parachute or staging operation?
