Brandi Mueller worked as a captain of scuba diving boats where she met some professional underwater photographers.
Though most of her images are of marine life, some of Mueller's most stunning pictures in the sea are of structures that do not belong there.
"Seeing the planes is really surreal," Mueller wrote in an email of the WWII aircraft she photographed off the coast of the Marshall Islands in the Pacific Ocean. "For some reason it's much more interesting than ship wrecks underwater. You expect ships to end up at the bottom of the ocean, but not planes."
The airplanes, which she said she didn't discover, are especially challenging to shoot because they're in deep water.
"You have a limited time you can stay underwater and shoot," Mueller explained.
Mueller took the photos in 2014 and wrote on Facebook at the time, "Please forgive all the airplane photos...I just happen to think airplanes underwater are really cool."
We don't think any forgiveness is needed — the underwater airplanes are totally cool.
