Chat has once again led me to ask a question.
Geoffc suggest that the "two bottom feeds were from the same camera" as they aimed at the same landing site. I then started to collect some images to see if they were indeed identical (listed below):
Image 1: Booster footage showing the ignition of the other side booster with identical orientation.
Image 2: Pre-separation, The land is clearly identical in orientation, although the flame is only nearly identical.
Now I'm of the opinion that the same identical camera was used, this is especially clear at the end, when both cameras are shown aiming for LZ-2. But was this the case throughout the flight? Or did something go wrong shortly before landing requiring them to resort to using the same footage twice.
