So I have tried the command AircraftDronesUnstuck many many times and increase the destination coordinates modifier. I still have 3 drones that will not land. Now they are circling my start point. Ideas how to get rid of them?

If you set the modifier to lets say 1000 it should definitely work, unless the planes origin hangar is not available (removed/no runway/...).
You can also create a debug file with the command AircrfatDronesDebug and post it here, maybe I can find out more with it.

If nothing works you need to shoot the 3 planes...

Here is the Debug File. Tried the UnStuck andLockdown commands. They keep circling around my spawn point. How do I shoot my own planes?
Thank you

This tells me, that this hangar on the map somehow "lost" the connection to its stored variables. The 3 planes probably came frome that hangar.
This means that probably during building or removing of the hangar something went wrong. You can use the command AircraftDronesCleanup to cleanup the script variables, and you should rebuild your hangars afterwards (do that manually and not with robots).
