SBU sources told BBC News it took a year and a half to organise the strikes. "The SBU first smuggled FPV drones into Russia, followed later by mobile wooden cabins. "At the right moment, the roofs were remotely opened, and the drones took off to strike the Russian bombers." The latter base was not mentioned by the SBU sources.
