Orbital Drum???

 I just watched an old episode of "Nasa's Unexplained Files".  There was a story about an astronaut orbiting Earth solo in his space capsule.  Out of a relative calm, the astronaut heard loud banging on his vehicle!  The striking of the capsule's metallic surface from some unknown source went on for a small amount of time and severely frightened the astronaut who called out for a reply to whatever was responsible for this racket.  Seems pretty incredible but the astronaut was convinced that he had some manner of lifeform shadowing his mission and as a consequence, messing with his head, Big Time!  Eventually, the outer hull racket abated and no answers were to be had of who this potential intruder was, but, HOW CREEPY!!!! Was the space capsule being used as an Experimental Musical Instrument?  An Orbital Drum, if you will?  We can only speculate....

Here is a VideoGPT AI retelling of the situation in its own analysis!  Enjoy.
