I was able to find some footage of POTUS' 21 gun salute, though it's difficult to hear the first few shots, I counted at least 18 shots & all spaced 3 seconds apart. (https://youtu.be/oCaGRDfLXc4?t=1470)
Speculating here: POTUS took the oath of office on Marine 1 after the bird stopped & before he exited. That's why all SCOTUS Justices were not at biden's faux-inauguration, those not at joe's were on Marine 1 with POTUS to administer & witness the oath. When he departs Marine 1, they play Hail to the Chief & perform the 21 gun salute. POTUS Trump then goes on to give his post-inauguration speech.
As I said, just speculating & I'd welcome any corroborating or confuting evidence.
