Coats said the U.S. doesn't have constant or consistent spying of the traditional kind in North Korea, in terms of people on the ground gathering information. To underline the nation's lack of widespread modern infrastructure, Coats referenced a NASA satellite image of North Korea at night. This photo of North Korea at night was taken in 2014 from the International Space Station. The rings running around the fuselage indicate North Korea is using an advanced filament-model airframe. That claim — far from confirmed as fact by the analyst community — is rooted in pictures of North Korean engine tests.
