A landing aircraft has priority over one taking off.
Its not practicable to overfly and look at a windsock on a jet. So you use the AWIS and your onboard instruments with a wind vector.
If the tailwind exceeds your landing capability you get out of there.
As for the aero commander, taking off into the path of an incoming jet who’s been making appropriate radio calls. Along with the AFRU. Sounds like just another GA pilot in a rush who messed up and passed the buck.
