    David Pike, you wrote:
    "Well done Tracy.  It’s lovely to see someone still using celestial in an aircraft.  Which sextant were you using?  Was it in a mounting, or was it hand held?  Did it have an averager, and was it a mean or a median type."

    I don't know if you remember Tracy Shrier's name from the announcements for the Navigation Symposium. He did a truly excellent presentation on his experiments in celestial navigation, and the extensive visuals accompanying it are available for download at fer3.com/mystic2017/. You should definitely have a look at that. It will answer some of your current questions, and no doubt raise many more questions!

    While there are quite a few people around today who have experimented with aerial celestial at low altitudes and many, like yourself, who had extensive professional experience decades ago, Tracy Shrier is the only one I know who has done this regularly in a commercial airliner at cruising altitude just below the tropopause.
