All of out local news media at the time....with a near zero radar profile but for the rudder(maybe) and coming in at a very ground hugging height he managed to elude all the roof top Secret Service aerial surveillance until they had visual sighting by Capitol police.
Matthias Rust did the same thing landing his Cessna 172 (IIRC) within the Kremlin walls in a much longer flight within the Soviet heavily defended border. Most embarrassing for the commies.
Just imagine what a much smaller drone(s) could do

Ecclesiastes 10:20
Curse not the king, no not in thy thought;
and curse not the rich in thy bedchamber:
for a bird of the air shall carry the voice,
and that which hath wings shall tell the matter.
