'Russian bombers are burning en masse' — Ukraine's SBU drones hit 'more than 40' aircraft in mass attack, source says

An operation by Ukraine's Security Service (SBU) using first-person-view (FPV) drones smuggled deep inside Russian and hidden inside trucks has hit 41 Russian heavy bombers at four airfields across the country, a source in the agency told the Kyiv Independent on June 1.

The operation — codenamed "Spider web" and a year-and-a-half in the planning — appears to have dealt a major blow to the aircraft Moscow uses to launch long-range missile attacks on Ukraine's cities.
