"Russian Spy Plane Flies Over Washington, US Military and Nuclear Bases"

Thanks to the Internet web site Zero Hedge and the article by Tyler Durden

"In accordance with the 'Open Skies' treaty, which allows the US, Russia and 32 other countries to carry out inspections of others' military infrastructure on their domestic territory, typically via spy plane, Russia carried out its latest reconnaissance flight over American territory this week."

This video from You Tube even shows one operator at his station operating the on board equipment. That airman speaking apparently is a Dane. Certification from USA lacking in 2014 but now has been granted?

"A Russian Tu-214ON spy plane made a reconnaissance tour over the southwestern US, capturing images of military bases and nuclear and chemical weapons caches. On Wednesday, the Russian plane was spotted over Washington, DC conducting low-altitude surveillance (and probably scaring a few unsuspecting locals)."

OPEN SKIES the concept for aerial surveillance of this sort first proposed by President Eisenhower in 1955.

OPEN SKIES now a reality many decades later.
