Say you're flying an amateur-built plane just out over the waters of, say, Alaska. And then you encounter a fleet of maybe 5 foreign military jets directly above you, and then you get radio transmissions from the group in Russian. Well, what should a pilot do? The pilot doesn't understand Russian and is clearly not over any foreign airspace as the pilot is flying less than 20 miles south from the shores of Alaska, which shouldn't be somewhere that foreign military jets should be scaring pilots.
Would heading back to shore really be a good idea? The jets could potentially be hostile. So, what would be the wisest decision in this sort of scenario?
