Queer Trader .... Avionic and Radio Tech's
( you gotta be queer to understand that stuff ) ...in modern terms ' a Nerd '
Although...those Avionic and Rad' Techs were on pay level 6 which was the ' highest ' pay level for ' ground crew '
Us humble Aircraft Engineers were on pay level 5 ... apparently we aren't smart enough for pay level 6 .
Good one Hans
