As a long time flight nav (old), I know from an aviation point of view, in the weather, night, turbulent flying, star observations to be difficult, especially with a hand held sextant as flown in the 30s and early 40s. Even worse was a sextant with no averager! One great improvement that was so simple: was the sky-hook. You could they hang onto the sextant and be somewhat more stable in your effort to get a sighting. An even worse condition was when the battery that supplied power to the bubble lamp went dead... you were all but sunk! I often wonder if that was Amelia Earhart's Nav-Noonan's problem on his long 20hr flight in to Howland Island. He had all of the above "worse conditions."
