I almost missed it.
The news is a week ago, but it has not lost its relevance:.
The FSB arrested two natives of Transcaucasia who were preparing terrorist attacks using drones on air defense facilities and energy infrastructure in Moscow. This was reported on October 26 by the Public Relations Center of the FSB.
According to the FSB, the attack UAVs obtained from the caches were supposed to be ready for launch, transported to the Moscow region and activated before take-off, and further control would be carried out remotely from the territory of Ukraine. The arrest took place during the preparation phase for an attack on an electrical installation and one of the key components of Moscow's missile defense system.
One of the detainees, as the department clarified, was recruited by an SBU officer and came to Russia for a promised reward, then recruited his close friend. They took FPV drones and components for improvised explosive devices from caches in the Smolensk and Kaluga regions.
I think this brings us a little closer to the answer to the question of how Ukrainian drones "reach" Omsk, Tyumen, Yamal, etc.
