The second example utilizes the testrunway.
I've found you need the testrunway to landing properly and despawn of AI craft (you certainly don't need this for all HUMAN flights):

(the testrunway is one of the AREA-based runways, not one that has a raised cement or whatever). They show up as a red-colored area).
