Thanks for the links. I agree with the speculation of a high G blackout. The pilot made no attempt to recover the aircraft.
I stand corrected. I saw Juan Brown’s blancolirio channel analysis on YouTube, and it follows the GLOC (G-force Loss of Consciousness) pattern.
Apparently, the 61-year-old pilot in the red jet was leading the blue jet who then passed him on the outside. He then realized he was going to cut inside a pylon and be penalized out of the race, so he swung out at about 500 mph and then overcorrected to get back in the loop. It was then that he pulled enough g’s to blackout and lose control close to the ground. The right aileron actually came off from the overstress, but it would have been recoverable if he hadn’t blacked out. He actually had the best qualifying time in his jet but was fairly inexperienced with this gold level racing and made a “rookie” mistake.
