    Of course, if you have an astro compass, you really need an aeroplane to demonstrate it with.  I christened this one ‘No Sun Dorma’, because every time I tried to use it, the Sun went to sleep.

    I noticed that the side windows of the Shackleton MR3 at Newark Air Museum have what look suspiciously like astro compass mounts fitted.  As the aircraft already had apertures in the roof, I’m assuming that that the ones at the side were for use by additional crew member/observers reporting surface sightings.  Did you have similar fittings in the P3 Orion?
