N334AA (flight 11 on 9/11) in Zurich

In a documentary from 1992 about Zurich Airport, a Boeing 767 with the registration N334AA can be seen. This is the aircraft which years later in 2001 was hijacked by terrorists and flew into the world trade center tower 1.
In this footage, they alternate between N334AA and N338AA, so it's not always clear which aircraft is shown. Here is my take on it. Please leave a comment if you have inputs:
0:14 Scene 1: unclear (but most certainly same plane as scene 4). From the angle it looks like gate 33 (therefor most likely not N334AA).
0:27 Scene 2: not N334AA because in scene 3 the tires seem to be wet (here they are dry)
0:30 Scene 3: N334AA (label visible on the hatch of the gear). From the angle it looks like gate 33.
0:36 Scene 4: unclear (but most certainly same plane as scene 1)
0:40 Scene 5: unclear
0:45 Scene 6: N334AA (label visible)
0:48 Scene 7: unclear
0:53 Scene 8: unclear
0:56 Scene 9: unclear
1:00 Scene 10: N338AA (label visible)
1:03 Scene 11: unclear
1:07 Scene 12: unclear
