That departure did not bear any resemblance to anything for which hard-and-fast procedures had been developed. Much like is beginning here, there was second-guessing on the entry, procedures, and recovery, all after the fact.
I can say with absolute certainty that they were not considering the oil sumps and fuel proximity to the pickups during the recovery.
That is wild to think about practicing something like that in that big of a bird- in it. Not in a sim for it. Your right though. They move with urgency but stay pretty chill.
How many all-up and operating MD-XX series airplanes have you seen do a "garden variety over-the-top stall", especially one that ended up ~80-90 deg nose low? With the exception of the airframe in that video, the answer is approximately zero, I'd bet. I'm not questioning your experience, there just aren't many - whether in flight test or fleet ops. This one got a lot of attention as much due to its rarity as the spectacular nature.
Because the flight characteristics of the airplane should mitigate the risk of encountering this extreme attitude, and because they're not designed for the nose-low high rate of descent potentially-overstressing and overspeeding condition extreme attitudes (not just 'unusual') tend to introduce. Even when flown within design limits (or maybe *if* flown within design limits...) it takes a LOT of altitude to recover and is fairly sensitive to technique. The test point in the video was not intended to develop into an unusual attitude.
Jet engines wouldn’t be very practical for high-energy tumbling aerobatics. They don’t have the instantaneous response that pistons do, plus their fuel consumption would be prohibitive.
In August 2014, the aircraft registration was transferred to Air 20 Corp in Gardnerville, NV, which just happens to be where the pilot, Antonio Pastini, lived at that time. Some news outlets are stating he still lived there, others give an Oregon address.
It's pretty clear Pastini owned the plane for over four years. I'll just guess he had some PIC time in it before the crash on Sunday.
We had an incredible incident near here just a few years ago in Greensboro, NC. A woman ran a stop sign at a T-intersection, jumped the bank, and went nose-first through the roof of a group home where adults with autism lived. They had pictures of the tail of the car sticking up through the roof. Miraculously, no one was injured.
His daughter is saying he owned it for a year, and during that time he replaced an engine and had the plane repainted...that is a lot of down time.In August 2014, the aircraft registration was transferred to Air 20 Corp in Gardnerville, NV, which just happens to be where the pilot, Antonio Pastini, lived at that time.

Recovery from unusual attitudes or aerobatic training, and similar is valuable in my opinion.
But, have you ever seen anyone flying a GA airplane do this training, or apply it, in IMC?
We had a similar one. A woman ran a stop sign at a rural intersection and her car was T-boned by a semi truck. The truck driver was not wearing a seat belt and was thrown from his seat in the collision, becoming a passenger instead of a driver. The truck continued off the left side of the highway and went through the lunch room of a school. The kids were all outside for recess so none of them were injured. (If you hear me advocate that commercial drivers should summarily lose their licenses for driving without a seat belt fastened, this incident is why.)
Well, you said, "That departure did not bear any resemblance to anything for which hard-and-fast procedures had been developed."
Yes, to calibrate the AoA vanes. I've known a couple of pilots who have found themselves upside down doing these tests.
But you you get the t-shirt?
When demonstrating high-AOA flight, are those planes' wings fully stalled (wing has exceeded its critical AOA) or do they just have an obscenely high critical AOA? It seems to me that the wing is still generating enough lift to overcome gravity and the plane is just deep into the back side of the power curve. But maybe that's not the case and you're riding on top of engine thrust. Sincerely curious question from a guy whose only exposure to fighter jets is trying to go deaf from the sound.
It's more complicated than that. Critical AoA is a simplification that works well for non-swept wings with no leading edge extension. Also, its the airplane generating lift, not just the wing. The lift curve for tactical jets is generally determined through at least 180 degrees (+/-90) angle of attack.
Thanks missed that
It sounded like normal circling to me. YMMV.
