BUREVESTNIK MISSILE
Russia has tested a new nuclear-capable, nuclear-powered cruise missile named the Burevestnik, Russia’s top general told President Vladimir Putin. The missile travelled 14,000 km (8,700 miles) and was in the air for about 15 hours, General Valery Gerasimov, chief of the general staff of Russia’s armed forces, told Putin. Putin has said the 9M730 Burevestnik (Storm Petrel) – dubbed the SSC-X-9 Skyfall by NATO – is “invincible” to current and future missile defences, with an almost unlimited range and unpredictable flight path.

Taking 15 hours to travel 8700 miles suggest that they either mailed it, sent it by bus or had it flying in circles for much of a day?
Also I don’t recall seeing many airplanes flying alongside cruise missiles while filming them over the years.
Something doesn’t seem correct in this story…….
