p.s. you did not reply to the question with the sparrow

Well received on the 20th July ; thank you very much!
I am sorry for this last response but the button had been transferred in Brittany, where I had no internet link...

Best Regards,

Although you can't tell, I put the ends right on the coordinates, perhaps with a meter of error (at most).

By comparison, I am a (relatively) pedestrian 825 kilometers distant.

Edit: To be fair, the crow would actually fly a bit further than the advertised number, due to the fact that the crow flies at a strictly non-zero altitude.

Wouldn't a great circle route be shorter?

...that is the great circle route.

Got my piece of math history, a bit crumpled from the transportation, it was squeezed between some other envelopes and the wire from the hook of the clip pressed against the surface, and almost went through the chin of the guy, but hey, it is a nice button and I really love it. Added it to the collection. Also, according with the international stamps on it, it costed xyzzy more then 10 dollars! I really appreciate the honor! Thanks.

It was only $3 USD and a very scary (Fill it out wrong and go to jail?) customs form.

I was going to say. I once mailed a bunch of CD's (sans cases it came to ~1/2 kilo) to Siberia and paid ~10 USD to do it.

That is not the same, they have cold winters and snow during all the year, we have hot all the year and floods during the summer only ...

Got mine yesterday, thanks a lot! Shipping to Germany was $3 also, so as long as it's overseas, it's always the same?

So far that has been the case.

But we have not shipped a button to Antarctica yet.
