I know that Mflight will be attending this amazing event.
I was trying to gather information and so far I have only been able to touch base with this website.

Looks like 24th July according to that lovely site. Also just saw a few things from the past events but nothing to help us this year
I want to see who all is comming or "flying" into Germany to be at this amazing event.
