4:23am A moment I particularly like to contemplate, commonly forgotten, is that tiny moment between night and sunrise. From 40 000 feet, flying eastward, we have the chance to see it very well and progressively, and it's always impressive to see how the night welcome the blue sky, well before any sun rays reach our eyes. It's such a beautifull gradient, with very deep tones it almost feels liquid. I particularly like that at that moment there was still a shiny star here to salute the daylight.
