The U.S. has resumed spy flights along the Eastern flank of NATO after intelligence efforts were diverted to Southwest Asia in June. An RC-135V Rivet Joint signals intelligence aircraft, flying under the call sign “JAKE17,” took off from a British air force base on July 8 and crossed friendly airspace in Europe, making its way up to Finland via the three Baltic states of Estonia, Latvia, and Lithuania, according to analysis of signals recorded by the website Flightradar24 by Newsweek.
