December's #avgeek gallery: 30 cool aviation photos

Hello, Today in the Sky readers! It's time for the December 2018 edition of our "#avgeek photo gallery." For the uninitiated, it's a batch of the fun airplane and aviation photos from around the globe.
Our #avgeek gallery first launched in January 2015. Since then, it has become a permanent monthly fixture thanks to popular demand from readers. As with previous editions, most of this month's the gallery is the handiwork of photographer and Today in the Sky contributor Jeremy Dwyer-Lindgren.
You can see the December 2018 photos in the slideshow above. Or, for more, scroll down to see the past year's worth of previous avgeek galleries as well as some other of our most popular galleries. Perhaps you'll find some new favorite photos ...
