Aviation Enthusiasts: b787-9 in a KLM Orange Pride Livery.
Aviation Enthusiasts Friend: What?
How do people differentiate different planes? E.g. How do you tell a 789 from a 788? How did you differentiate Boeing, Airbus, etc.?
What are some key features to look for when spotting a plane that is 100 - 500 ft above you? How do you see the airline livery against the sun and it’s 100 - 500 ft away?
