On Youtube for this clip from Russian MoD. Can you see the missile? I don't, no matter how I played with it:
In accordance to Russian MoD Kalibr missile covered 250 kilometers in 137 seconds before hitting the target in the Crimean Peninsula. This is Mach=5.5 land attack missile. Are we yet again in "Revelation Mode"? Let's wait and see, but this Zvezda article (in Russian) has this funny phrase: Initially, when missile accelerates, supersonic fighters which follow it are practically equal (meaning following) with it (c). And then, and then... I guess this was THE message. Make your own conclusions. Many people already did.
