Now imagine if the Ukrainians could take a few clapped out airliners that were heading for the scrap yard. A 737 sized airframe could easily carry 10 tons of explosives and 50,000lbs of fuel. Now that would make one helova mess it it plowed into an oil refinery. Surely 5 or 6 barely airworthy airframes could be scrapped up around the world for one final flight.
While their AD seemingly can't detect small light aircraft (as also proved all those years ago with the Mathias Rust flight) its highly likely it would be able to detect an airliner, especially given need for civil ATC etc.
