Ars Technica: Declassified photos from U2 planes are helping archaeologists unlock the past

Ars Technica: Declassified photos from U2 planes are helping archaeologists unlock the past. “During the 1950s and 1960s, US spy planes made regular flights across Europe, Central Asia, and the Middle East, photographing the terrain to track military targets. A chunk of the Middle Eastern photographs were declassified in 1997, and now those airborne images are helping archaeologists track changing features in the landscape that in many cases are no longer visible today, according to a new paper published in Advances in Archaeological Practice.”
