The world's hodgepodge of military bases run the gamut from hazardous mountaintop forts to seemingly impenetrable underground bunkers. Then there are bases on remote islands tracking objects in deep space and high-tech laboratories probing the most lethal microbes in existence. The design of a base needs to address the immediate needs of a military while still being versatile enough to remain useful as threats and technology evolve. We tracked down some of the most interesting active military facilities and spoke with Brad Schulz, vice president of federal architecture at HNTB, about why they're notable.

Here, PM explores the world's most remarkable airports and why they stand out.
