Around 4:30 PM from the terrace, a Qatar Airways B777-300 at 35,000 feet (10,668 m) and a Cargolux B747-4F at 34,000 feet (10,363 m) crossed paths – a mere 305 m between the two!
A change of scenery with a truly perilous crossing. 😲

It seems OK. 305 m=1000 ft.
“Vertical separation in aviation is the mandatory minimum vertical distance air traffic control (ATC) enforces between aircraft to prevent mid-air collisions, typically 1,000 feet below 29,000 ft and 2,000 feet above it, but can be reduced to 1,000 feet in Reduced Vertical Separation Minima (RVSM) airspace for equipped planes, ensuring safe, efficient use of skies.”
This separation can be safely maintained by modern autopilots.

Yes, it sounds pretty scary, but the technology is here. I read a book about the Panavia Tornado. There, the robot does high-speed, low altitude, terrain-following flights, and the pilot just watches the stunt with wide eyes.

Nevertheless, it's still impressive, when you consider the possibility of a head-on collision at over 1700 km/h.

A circuit diagram is merely a theoretical concept.
But to err is always human.
