Did we have Ancient geeks?
Start a timer that will count down the number of seconds from 52! to 0. Then walk around the Earth’s equator with one step every billion years. Then, after you make your way around the earth equator (by taking 1 step every billion of years), you take one drop of water out of the Pacific Ocean. Then, you repeat the process of walking around the equator, and everytime you walk around, you keep draining one singular drop of water. After the ocean is fully drained, you refill the ocean and put a piece of paper underneath you. Now, you once again repeat this process of walking, draining, and placing papers. After your stack of papers has reached the Sun, you repeat another 1000 times.
After all this, you have completed just about a third of the timer.
maintenance/acceptance test pilots test the aircraft within its flight envelope (safe operating limits), while test pilots help discover and define that envelope.
Yes, his survival instincts were correct choosing priorities of what to solve first.
>>That must be what people mean when they talk about "flying by the seat of your pants" XD
Yes, its butt-flying!
First I was just wow!
Then I read the PDF from 2013 blog and little bit of relief came from knowing that he was qualified pilot too.
But there is a big but! Before that, he flew dramatically different, slower only propeller planes, no jet, no supersonic jet. I can imagine that it kinda might be smth like having driving licence, but being put into an F1 car and asked to handle it properly in order to follow the track in highspeed, but in 3D.
Anyway, I recall my first flight on L-39 after having 20h on Ulla and 50h on Z-142: it was the same flying one is used to, but since releasing the brakes on runway the speed makes the biggest (initial) difference. And then the landing. Otherwise flying is always the same, same flying controls, what changes is the avionics, speeds, g-loads and capability to do certain manoeuvres.
Regarding speed jets are obviously different level fast from propeller engine planes, landscape runs below you way much faster than you are used to. Higher speed means less time for decision and reaction, no time for "wait, I need to think something over", because times flies and jet flies with it, fast. Nobody waits for you and your pondering there. Its totally different workload.
"I needed to get the feel of the aircraft, if I was to get it back on the ground". "..how does one interpolate or extrapolate Tiger Moth, Chipmunk Harvard flying to a two engined, 11 ton, beast like the Lightning?" That is exactly it. Get to feel the aircraft comes with time and experience, especially with final part of the landing (hovering above runway) your brain and eyes need to learn to see proper angle shown to you by instructor.
The most difficult to initially learn is the proper flare phase, when you transition from the approach to the actual touchdown. During final seconds you learn to feel through your butt the rate of descent - you coordinate butt feeling of descending (less speed means less lift, thus more descending) with hand pulling the stick to compensate decreasing speed with increasing the angle of attack (thus increasing lift), you smoothly balance this dynamic imbalance, you slowly decrease speed, increase lift and slowly decrease the height above the concrete in order to land smoothly from desired height. If you overcompensate (pull too much), plane can jump few meter up in the air, which you dont want (being higher with decreasing speed means you can just stall/fall on runway from few meters), if you undercompensate you will hit the ground with sharper descend angle sooner and with higher speed (which can start the sequence of hits and jumps that need to be taken under control). Practice makes you learn from these mistakes, make corrections for the wind aspect, air temperature (extremely cold or hot makes difference) ,take into account different configuration of aircraft, different fuel weight affects this too.
So there is a lot of trial and error and time needed learning to land safely. All in all, it took everybody ~10h before our instructors let us fly first jet solo. Of course we could crashland sooner with less experience.
Well, to conclude, every landing is different and every airline passenger can confirm, that sometimes it can be even adventurous.
I am sharing all this just to show, how extraordinary his landing was! Kudos!

Who can create money, who can access it, who can change the rules, who can freeze or censor transactions or even weaponize whole financial system?
What I dislike about fiat is that inflation is treated as a (wanted) feature while it is a cost paid by plebs via Cantillon effect.
All Govs keep rolling debt burden being paid with more debt.
Paper backed by paper and/or trust into goverments only. History and significant part of the world shows that this trust is being failed too often.
How sustainable current system is?
