I wonder how far apart those planes are flying from each other?
It's fair to assume they were close
. Airbus might have chosen to play tricks with a long lens, but in that case apparent distances (say, between windows) wouldn't decrease so much as you look at each plane further away.
Could probably estimate separation (in z) with a bit of maths based on the apparent length of each plane, but that would be too
Anything similar for Boeing?
