It still amazes me that people - lots of people - can enter a tube which rises high in the sky, then travels at more than 500 mph to a destination, then can safely land at that destination! Never lost a sense of awe that such a thing can be done.
And of course the view! From miles up in the air you can look down to see entire cities and towns, along with the surrounding topography. Not to mention sunrises, sunsets, storm clouds with lightning, and occasionally other jetliners passing underneath or overhead to their own destinations. Even some airline pilots appreciate their unique vantage point, and
carry along a DSLR to take pictures from the cockpit when
something amazing appears before them.
One of the most memorable sights I've ever seen was on a flight over the Swiss Alps going from London to Athens. It was a crystal clear June day, and the gorgeous mountains with their snowy tops were passing below when I spied a jetliner going the opposite direction underneath our flight path. I will never forget the beauty of those mountains along with the uniqueness of seeing the other jetliner passing below, leaving its contrail as if bisecting the scene.
On this trip up to Canada I was fortunate enough to get a window seat far enough back in the cabin to (mostly) avoid the wing or the engine, and decided to grab the Bigger Cahoona to try a few shots. It was not without its challenges, however; you're in constant motion, and need to be careful not to bang the lens against the window. And it's important to have lens cleaners handy to wipe the film and nose prints off of the window before beginning.
So I did those things and took pictures of what I considered to be interesting, this being the first one. In spite of the precautions and cleaning of the window, a lot of post-capture was needed to yield a passable snapshot, as can be seen from the original below:
