This plane (IRL) has the two rear-most windows deleted on its right side. In the IF version this is correct if you are at a close camera view, however if you zoom out the windows appear. See pics below
I have a feeling this is a glitch with the system that FDS implemented where when you zoom out, details of the model disappear and appear
Thanks for the report. I will relay this to the devs and we’ll look further into this :)
