The U-2 is a single-jet engine, ultra-high altitude reconnaissance aircraft operated by the United States Air Force (USAF) and previously flown by the Central Intelligence Agency (CIA), used to provides high-altitude (70,000 feet), all-weather intelligence gathering. WSJ journalist Michael Phillips was fortunate enough to tour both the U-2 as well as the film processing lab at Beale Air Force Base in California. Any photos, which are shot on 250-pound rolls containing 10,500 feet of 6-inch-wide film, captured with the wet-plate camera onboard is transported by FedEx back to the base in California to be developed.

"The 1950s camera, combined with the U-2's altitude, provides formidable photo capabilities: it can cover every inch of an entire country in a single mission.

Using loupes and microscopes, analysts can distinguish objects in the resulting photos that are just 8 inches apart on the ground - enough resolution to read the numbers on the wings of a parked airplane," reports Peta Pixel.
