... Not actually anything to do with this thread/comic, but it just occurred to me to share it, rather than let it sit unused and unloved upon a memory card for the foreseeable future.
Too easy? Well, I reckon the basic model isn't that much in doubt.
(What's that site that you can look up global commercial aircraft movements on? I could probably narrow it down to an actual flight, if my camera clock isn't too far wrong...)1
It's a quite old camera, only my 'carry around just in case' one. Only a 10x maximum optical zoom was available, and then I also cropped the whole massive image down quite a bit to just the rough area of interest. But at least I refrained from any digital zooming/interpolation along the way, so you've exactly the best detail I could give, without my having switched to a RAW format at the time (was stored as .jpg, but copied into .png so as not to add a second, shifted, set of JPEG artefacts). The sun was pretty much dead ahead of the aircraft, as you can see from the nose-glint; but still very slightly to the left, and above the flight-path too, as you can see from the tailplane shadows on the
