An unmanned aerial vehicle was scouting over the Russian Fakel plant. The drone went down on the factory premises, probably due to communication jammers.
Here's What We Know
The Fakel plant is located a couple of kilometres from Moscow, if we're talking about the border of the city, not the centre of the capital. The company manufactures the S-400, S-300, Tor-M2 and Osa surface-to-air missile systems.
According to the plant's security guard, the quadcopter was made by craftsmen hands. It was equipped with several cameras. Law enforcement authorities are already looking for the creator of the drone.
The security guard said that the drone has a size of about 30 cm x 30 cm. Due to its compact size, it can be argued that the quadcopter was launched from a nearby area.
