The B Word,
How I've managed to fly gliders, motor gliders and tugs for nearly 50 years without using "approved" thread to attach badges to my clothing is a complete mystery to me!
Never in all my years of aviation has a badge dropped off my clothing and caused a control restriction - I guess I've been lucky.
Maybe my "gashly tacked on badges" have looked rubbish, but they've never stopped my enjoyment of flying, nor affected the quality of instruction that I give, nor caused a flight safety issue.
However, what is evidently clear is that people like you, with a firm grip of hiding behind the utterly trivial and inessential, are the real reason that young lads have been denied the chance of gliding for two years.
Do you really believe in the utter garbage that you post?
