Closest airport

Thank you sir

nice, but lots of ads. Also not terrifically handy.

I first put in Thun, Switzerland. No such place. Uh, yeah, yes there is.

Then I tried the other end of the lake, Spiez.

Result:

Bern Airport (18.3 miles / 29.5 kilometers)

EuroAirport Basel Mulhouse Freiburg (63.0 miles / 101.5 kilometers)

Aosta Valley Airport (67.2 miles / 108.2 kilometers)

Zurich Airport (67.4 miles / 108.5 kilometers)

Fun, but not a whole lot of use, unless you're a private pilot. The only practical close airport for commercial flights is the last choice. You could also have had Basel (in position 2 but that's fairly small too) or Geneva but the tiny airports didn't leave room for Geneva.

Thanks for adding it Lane, perhaps it is more use in other parts of the world.
