Pilot is obvious and pimpf is German for a colloquial name for a boy before the voice change, thats long changed now , I'm even a proud father now !!!
Pimpf also means a young inexperienced person , what I was when I started flying the demo of this many years ago..
Der Pimpf was the Nazi magazine for boys, particularly those in the Deutsches Jungvolk, with adventure and propaganda and this is where a lot of young people got the urge to fly, gliders firstly (done that ) then the Luftwaffe called!
Just like any young boys magazine or comic with pictures of daring do in the air.
As a lad I always made Airfix models of the German planes because they had fancy badges whereas Spits and Hurris where very plain and boring.
So a long time interest in the Luftwaffe and then Pha3e beautiful artwork on my favourite aircraft clinched the avatar.
Bit more experienced now thankfully , a lot less crashes.....LOL
