is to fly from the East Coast to the West Coast just at sunset or sunrise, if you’re super lucky and the timing is just perfect you get a sunset or sunrise that is continuously changing and lasts for more than an hour as you fly towards the sun and the sun moves away from you in the sky, or fly away from the sun and the sun moves towards you. It happened to me once, and I spent the entire time staring out the window at the changing landscapes and clouds over the seemingly never-ending sunset. It was amazing.
