A plastic sextant equipped with a practice bubble attachment might be good enough to perform inflight CN on commercial flights. I would be interested in the results if anyone on the List gives it a try. Observing through a jet cabin window using a conventional sextant with a bubble attachment will have a limited field of view compared to the aircraft bubble octant with a forward prism so plan for bodies to be at lower altitudes close to the beam of the aircraft.

Taking a plastic sextant aboard would be less problematic than a metal sextant or aircraft octant.

Several yeares ago, on a return flight from Maine, I had a Davis Mk. 15 with me, a carry on piece.

The security peson at check in, a lady, asked what was in the ehite plastic case. I told her it was "a sextasnt", to which she responsed with a double take or blank look. When I opened the case for her she said "oh a navigastional instrument", to which I responsed yes, going on my way, without additional question.

So much for my adventures with the air transport of sextants.
