This is a reactivation of two airports deleted in sim update 6 today.
The airports are -
EDDT Berlin Tegel
KPFN Panama City–Bay County International Airport
I'm sure a few people out there are fond of them and wish for them to live again.
EDDI Tempelhof, which was also deleted in SU6, has been reinstated and worked on properly by someone else here - https://flightsim.to/file/23472/eddi-berlin-tempelhof-complete
I haven't done anything to them apart from reinstalling runways at Tegel to give them light again. When Asobo deletes airports they leave everything intact, all they do is remove the airport object to make it selectable.
The 'main file' when you press the download button is EDDT Tegel.
If you want to do more yourself then I've also included the project files to download. Let me know if you've improved any and I'll take the version here down.
