Dook asked if it was one of the poles ( as a region)
I thought Chevron by asking if it would the South Pole in order to reduce the search area by 50%.
(as no airbase name was given)
If the challenge had been about Luxembourg I would have accepted Luxembourg as a correct answer as they only have one airport (of which I am aware)
It is indeed Marambio as Dook stated.
The only non ice strip on the South Pole
dook has control again
(and I myself, appreciate that you give others some time to come up with their own answer.
Although I can also see that others would be annoyed that you show to have more time to spent as them)
