I did a course on cartography a couple of years ago, and one of the better assignments was to find a suitable projection and make a proper map describing a comparison in distances between two points. The projection I used was of course Two-Point Equidistant Projection (the only possible one). My resulting map is on the last page here: https://adelie.antarkt.is/aron/l0020b.pdf https://adelie.antarkt.is/aron/l0020b.pdf EDIT: Apparently it was one of my GIS courses, not the cartographic one, which were more color theory and labels. One bad thing about the projection is that great circles are curved, so my straight lines should have been curved as well.

LLA: the optimal hub — at least in summer. (and modulo transpacific routes?)

  The LLA freight proposal was given by the teacher in the assignment, but I guess there is a real benefit. Isn't Anchorage preferred over Honolulu for most trans-pacific flights?

    Hej. Sorry, I have no idea. https://www.flightradar24.com/ https://www.flightradar24.com/ makes it look like most flights are direct (too far south for ANC, too far north for HNL), but I couldn't quickly find any way to filter out cargo from pax. PS. Having just seen https://www.youtube.com/watch?v=5hdUKZLQIuQ https://www.youtube.com/watch?v=5hdUKZLQIuQ I have to ask if you all really chew snus? What savages — tobacco is for schnupfen. https://www.youtube.com/watch?v=oOa1cz7O3kU https://www.youtube.com/watch?v=oOa1cz7O3kU

      Haha, if you drive EPA you most definitely use snuff, in the mouth.

    Yes, Anchorage is a major freight hub. Apparently, fourth busiest in the world: https://en.m.wikipedia.org/wiki/Ted_Stevens_Anchorage_International_Airport https://en.m.wikipedia.org/wiki/Ted_Stevens_Anchorage_Intern...

  I remember there was much talk in the local press around 25 years ago about how Kallax/LLA was to be the next big freight hub. It went as far as extending the runway to accommodate bigger planes (making it the longest runway in Sweden, if Wikipedia is to be believed). As far as I know, the freight boom failed to materialize, largely because Russia were not very keen on allowing flights through their airspace. So we need a map projection that weighs distances by political resistance. :)
