And aircraft could fly at 0mph in a strong wind; it has happened. Indeed, an old british first world war trainer, the Farman Shorthorn, could fly at about 25mph or there abouts.
Yes 0 mph groundspeed but never 0mph airspeed. The only types of AC that fly at 0 mph airspeed are VTOLs and helis but even with the helicopter the craft still has airspeed over its wing which is called a rotor blade. One other unique thing about helis is once the craft starts moving forward the advancing blade develops more lift while the retreating blade develops less. So the whole rotor head has to teeter or be articulated or the copter will roll away from the advancing blade.
Again look at the B6 computers in the above photographs. These are used for calculating TAS do you see anything on the computer about headwind or tailwind. No because it does not enter into the equation. It has nothing to do with IAS or TAS.
