El Alto International Airport was temporarily closed following the crash.
The most turbulent flight routes in North America are over Colorado, where the prevailing winds from the west barrel into the high peaks of the Rockies and tumble onto the High Plains below. One morning this fall, on a stubbly brown field in Boulder, a glider pilot named Dan Swenson stared up at the sky and shook his head. A vast, lens-shaped cloud hung above us like an alien mother ship. It stretched from the foothills of the Front Range, in the west, to the Laramie Mountains, in the north, its pale upper reaches darkening to a gunmetal gray along the bottom. “So, what’s with this?” he said. He glanced over at Jordon Griffler, the scraggly young pilot who would tow Swenson’s glider into the sky with his single-prop plane. Griffler shrugged and took a bite of a bagel. “You can ride that all the way to Wyoming,” he said. Swenson shook his head again: “Holy cow!”

To minimize distractions when you're trying to sleep, the Dreamie's display will dim in response to the surrounding darkness. There's also a Redshift toggle to make the nighttime display easier on the eyes, a Dark Mode with a simplified appearance and the option to have the display turn off completely when you've been inactive for a while. I set the Dreamie on my nightstand close to where my face is at night, and I haven't had any problems with light from the display keeping me up.
