The Naudet Bros. did not have a commercial plane in the frame of their film.
It's a long dig on them as operatives.
But you can see for yourself by zooming and slowing it down that there is not a commercial aircraft depicted.
It's a suggestion.
The South Tower exhibited the CGI effect .
The North Tower was a fortuitous filming by the "Naudet Bros." [anagram "Duane st" where the firehouse they were allegedly there for was situated]
We don't know what they captured except that it was not a commercial jet airliner.
It may have been an unknown projectile.. "X" The sound on that clip was not authentic. And changed through various versions of the clip.
