Aeronautics Photos is a Mac app that helps you view about 350 unique images of American aeronautics from NASA`s archives, divided into three groups: Aircraft, Research, and Early Research.
Captions, all from NASA, are extensive—thousands of words. You can view images in a grid, or extra-large, or see a slideshow. You can also order prints.
NOTE: Aeronautics Photos can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
