Strange Airport location
I have found a strange airport location:
The Swiss town Basel (near the French border) seems to have two airports on the same spot (in France)
BSL Basel 47.590000 7.529200
MLH Mulhouse 47.590000 7.529200
I do not know which is correct. There are a number of airlines operating the roue BSL-MLH
(AF, KL, MK, OK and T7).
Does anyone know anything about these two?
