    I posted a lengthy report on NavList some years ago. Whilst flying a Tigermoth over the English Channel during a total eclipse, with navlights on, longitude was derived from timing second and third contacts, and latitude by the symmetry of the aurora. An alround horizon was visible, as was a planet. It was a good job cockpit lighting wasn't mandated, and no instruments were visible. No sextant was necessary.

    Flying eastwards, the length of the eclipse was extended by 12 seconds. I did not log extra night flying to go with the 7,000 hrs night command I already had...
