> “We don’t do things like that here at all. So, Vauxhall [MI6] will almost never outsource meaningful intelligence work to the private sector,” they said.

That one explains that "Vauxhall" is a metonym for MI6, whose headquarters is in Vauxhall.

> Still, trading in knowledge is commonplace. The same person added that there is a “lot of frustration from both sides of the river [Thames] that the old boys’ network was getting a bit too informal, with people telling their clients that they can call their old buddies.”

That one completely fails to explain that "both sides of the river" means MI6 and MI5 (whose headquarters are on different sides of the Thames).

> ACAS SSR radar did not detect anything

> As the aircraft and its attendant UAP/Light approached the Mexico/US border the UAP/Light began to flicker, it changed colors from yellow-white to pinkish/purple, and turned on a perpendicular heading away from the aircraft and parallel to the border without crossing into the United States

That’s hilarious.

> 1. The UAP/Light came from above and stopped/hovered near FL37, about the same altitude as the aircraft, shone a light on the 767 and briefly approached the aircraft. Then it instantly matched the speed, and heading of the aircraft and maintained a consistent separation.

> a. The light descended vertically, stopped abruptly, and shone a light on the 767 causing the crew to believe that there was another airliner on a collision heading with its landing lights on.

> b. It changed direction from vertical descent to a sudden stop/hover, to approaching the aircraft briefly, to taking the same heading and speed of the aircraft at about the same altitude and an estimated distance of 1-2k ft.

> c. It matched the altitude, speed, and heading of the aircraft, 575mph and at 37,000ft for over 32 minutes.

> d. The UAP/Light changed colors and turned away from the aircraft on a perpendicular heading, West, just inside the Mexico/US border.

> e. The UAP/light did not have wings or running lights. It was a new and unique observation to the experienced air crew.

Standard UFO behavior.

by analogy in cryptgraphy and security, remember that people used to get isolated and discredited as conspiracy theorists for believing-in or talking about ECHELON and any suggestion about a program like BULLRUN to backdoor algorithms would get you laughed out of rooms. somehow there was always someone within a degree of security projects to spread a rumor that someone was some kind of unstable or paranoid lunatic if they spent any effort trying to discover surveillance instrumentation.

I'd suggest that these UAP craft are protected by similar social mechanisms in physics.

Further, I think we're going to see many more of these limited hangouts of advanced propulsion and energy tech because as AI reasoning capability increases, it's going to discover classified maths and physics (ask it about cryptographic attacks now), and the establishment that manages that advantage is going to need to stay ahead of that.
