If you are enjoying the Jenny, you might be interested in our recreation of the US Air Mail system. Using over 1500 concrete arrows and flashing beacons, it allowed Air Mail pilots to navigate by day and by night along 34 routes.
Although the Jenny was going out of air mail service by the time the system was established our mod means that you can fly from Salt Lake City, UT to Pasco, WA by following 51 arrows and beacons without needing a compass!
We will shortly be releasing two more routes and ten landing fields.
