Happy to know that you still do that - so many folks leave their shades closed for the entire flight! I’ve been ‘looking out the widow at the world’ professionally for about 17 years, and still love to do it when riding around in the back.
This - what can I say - lack of curiosity, interest, awe, about our world - leaves me mystified. I could spend (and often do) entire flights gazing out windows; that, and studying the screen - the only screen I will ever watch on a flight - that depicts the flight path.
I love to do it, and far prefer it to anything else when flying - I loathe movies on flights; occasionally, there will be a compelling conversation with a fellow passenger, but, for me, gazing out that window (and glancing at the screen that depicts the flight path) is still a source of wonder for me, a marvel that I will never cease to enjoy.
Actually, to me, it is still a marvel that we have "manned flight" at all; I'm very mindful that it is just under 120 years ago since the Wright brothers tested their wildly revolutionary and transformative craft at Kitty Hawk.
I thrill to studying the landscape of countries and regions from thousands of feet (or metres) above ground, - it is instructive and thought-provoking to see how physical features change (as does the fact and extent of cultivation) and I still react with stunned amazement and stupefied delight - and awed gratitude - that I have had the privilege of working and travelling across three continents (none of them America, a continent I have never visited) and seeing stuff - with my own eyes - that I used to study with absorbed fascination in an atlas, or, while watching a documentary on TV.
The Horn of Africa, Lake Caspian, the Pamir and Tien Shan mountains, - even the striking - striking, because quite distinctive - coast of the Netherlands ("gosh", exclaimed the person who sat beside me, the first time I flew over the coast of the Netherlands on a flight from Russia, in the early 1990s, "it looks just like it does in an atlas", yes, it does), these are amazing from the air; and, flying from some airports in the less developed parts of central Asia - or, indeed, parts of Africa (and, back in the 1990s, the former Soviet Union and Central and Eastern Europe) - in planes that were no longer seen in western Europe - like scenes from the 1950s - were also amazing experiences.
