I went to a social gathering many years ago with a friend who is an airplane mechanic. His coworkers (other airline mechanics) were at the gathering, and I noticed some of them huddled around a screen watching video, which I assumed they had shot themselves.
The home movies were of commercial aircraft, especially takeoffs and landings. Mind you, these weren't scary videos of crashes or problems. Nothing malicious was going on. These mechanics just liked looking at healthy planes -- in their spare time, no less -- because they're beautiful and represent a job well done.
Along those lines, this slideshow is about beautiful machines and technology from NASA. It's hard to stop at 10 images, not just because the images are free and plentiful, but also because they're beautiful -- in the eyes of engineers.

At Work in the Destiny Laboratory of the International Space Station
NASA astronaut Mike Hopkins, Expedition 38 flight engineer, performs in-flight maintenance on combustion research hardware in the Destiny laboratory of the International Space Station in this image taken on Dec. 30, 2013. Hopkins replaced a multi-user droplet combustion apparatus (MDCA) fuel reservoir inside the combustion integrated rack (CIR). The CIR includes an optics bench, combustion chamber, fuel and oxidizer control, and five different cameras for performing combustion experiments in microgravity. Click here for a larger image.
