20km from the carrier at an altitude of 4000 meters with no gas in an F4F-3. I knew I didn't have a prayer of making it back to the carrier and landing so I didn't use the quick record (.ntrk) feature. Not only did I make it back I made one of the prettiest landings I have ever made even though it was a little long and I ended up stopping in the middle of the deck next to the island.
I saved a standard track (.trk) hoping it might come out OK but no such luck. I should have went with my first thought and clicked the .ntrk button...
