This was a EuroGA.org fly-in to Astypalea LGPL in Greece.
We do a few of these fly-ins each year but most go to near Europe (May 2018 will be Cambridge).
So this was a rare extra long one. Greece has become quite difficult and much more expensive following the Fraport (a German based airport operator) takeover of nearly all its money-making airports...
There are some videos in there too - enjoy :)
