Flying from Singapore to Sydney a few years back, after take off Captain makes a pa to pax about en route weather expected time of arrival etc.
Finishes pa by saying just about to fly over the equator and if you look carefully you'll be able to see the red line which circles the earth and is the equator..cue 300 odd pax straining to see the red line, one of which was clearly heard to say.."ooh look..you can see it!!"
