Not radar. Visual and IR .
Whatever, still just testing new stuff.
Not saying pro or con but what if on another day someone said they believe US stealth fighters and stealth bombers do not exist.
They weren’t tracked on radar coming in.
Anecdotal reports say birds flew away frightened as the purported planes landed and flight suited crew members got out of black craft and went to the base bar for drinks on their time off. What a story. No one will believe it, though. Didn’t show up on radar.
