As Americans were celebrating the Fourth of July holiday, four Russian long-range bomber aircraft flew close enough to the US shores that they were intercepted by military fighter jets. The first set of two bombers flew near Alaska and just 30 minutes later a separate set flew far off the west coast of California.

According to officials at NORAD the flights stayed within international airspace and at no time did any of the Russian bombers enter or get close to entering sovereign North American boundaries
