"why should pilots wear wings anymore than observers should"
I always thought "pilot" wings were just that, they simply meant you are the pilot.... you know, can fly the aircraft?
"Earned it" Yeah, you probably have if you have a fair bit of experience. The observer has not. He is part of the team, but not a pilot. It's not elitist. Does an Ambo put Dr in front of his name?
I have wings on the name tag on my flight suit, saves the medical guys on the ground from getting blank stares from me when they mistake me for a paramedic...
