Washington, D.C., United States—After much deliberation, the U.S. government has authorized a Russian reconnaissance aircraft to fly over American soil as part of the Open Skies Treaty.

Previously, the U.S. had declined to allow a specially equipped Russian Tu-214 aircraft to conduct such a flight.

U.S. authorities have now determined that the aircraft does indeed comply with the Treaty’s provisions. According to the U.S. State Department, after “an extensive review and inspection process involving experts from the United States and many of our Allies and partners. This process has verified that the Russian aircraft and sensor meets all Treaty requirements for certification.”

The Open Skies Treaty enables its 34 signatories to fly over each other’s territory and verify military installations, movement, and general activity. One of the Treaty’s key functions is to serve as an arms control measurement. Before any flights take place, the nations involved must coordinate to avoid any unpleasant situations.
