Are you certain they were really sextants on those naval aircraft? We used
an octant aboard a P-2.

In maritime history octants were the predecessor of sextants. Octants have
several distinct advantages over the sextant for use in aircraft. If you are
experienced in the use of both you can really understand why.

Perhaps your memory is not reliable.
