Hi there !
I'm an Air Traffic Controller in Bremen,at which the most famous Shift Logic is now in use on a 5-3 terms Shift.
It's true that there is a big lack of ATC Personell in Germany - not only in Frankfurt, nearly in every sector.
I support your wish for trained Staff in Germany - i ´have a lot of Feedback on my Website - World of Air Traffic control :
www.woatc.com - and i think i will add more about our Situation in Germany.
WE NEED ANY MAN !
Grüße aus Bremen !
