Fuck yeah I wore it in primary. The Ghosts of Aviators Past were Aviators at one point. Which probably means that a lot of them were common sense kind of guys. When it was cold, they wore a jacket. They'd probably want me to do the same.
I can't imagine why anyone would consider it bad luck. If anything, it's a connection to the past generations of aviators. How could that be bad luck? If anything, it'd be bad luck to wear black shoes and a swo-ter. Better be careful, if you dress like a SWO, you might end up one.
Oh, and if someone with wings if pussy-footing around about wearing it? That's pretty disgraceful.
I've seen multiple syllabus-completers waiting to wing wearing black shoes. I gave one shit the other day. Unbelievable.
