Sun-Moon Flat Earth Astrolabe

Invalid date

Fixes. Added sun visibility limit circle (green line) to aerial view. I matched it exactly at one latitude but doesn't work precisely for all, showing they have a distorted projection in the Google map. :)

Added over 8,000 airports which can be optionally diaplayed. The Google Maps aerial view can't handle so many markers so they are only on the AE map for now.

Added a "DON'T PANIC" button.

Minor bug fixes. Added location select and teleport feature to the AE map.
