Very interesting post.
I had this just the other day. I was at home in Bristol and was messing about on Flight Sim. I was flying over to KIAD and was replicating BA's actual scheduled flight. I took off first but kept an eye out Northwards to see if I would catch a glimpse of the real aircraft using FBOs' tracking service.
Long story short I never saw the real plane but whilst staring up into the cloudless Blue sky I had the same experience. I saw all these little white, ameoba (spelling?) type dots whizzing across my sight. Was a bit disturbing at the time as its the worst i've ever noticed it. I only notice it once in a blue moon.
More interestingly its colour related.
I'm pretty servely colour blind too.
