Ukraine seems to have fitted Cessna-style planes with remote controls, packed them with TNT & flown one 600 miles to strike a drone factory in Yelabuga, east of Moscow.
Tomahawks tend to fly a bit faster and have a more focused payload.
Doing a Flying Timothy McVeigh certainly creates a large explosion. I have to question whether this strike had a meaningful impact on drone production, any more than McVeigh's strike had a meaningful impact on the FBI's ability to operate in the US Southwest. A ballistic missile would have had the same penetration and done far more damage.
Federal building generally. It had a bunch of offices, including the DEA and the ATF. The latter is what he was (mostly) targeting, since it was (mostly) in response to Ruby Ridge and Waco.
