We are being asked to believe that a passenger with no flight training, armed largely with knowledge from television, stepped into the cockpit of a plunging Boeing 737 MAX and made precisely the right recovery input without destroying the aircraft. Before that becomes accepted history, show us the evidence.
Something extraordinary happened aboard Flydubai Flight FZ1073.
That much is not seriously in dispute.
There was a violent cockpit emergency. The aircraft made an astonishing descent. Passengers and qualified pilots became involved. The airplane eventually diverted and landed safely.
But buried inside those established facts is a much more extraordinary claim—one that has been repeated around the world with remarkably little scrutiny.
Israeli passenger Yaniv Hayun says he entered the cockpit during the emergency and pulled back on the controls of the Boeing 737 MAX, helping arrest its terrifying descent. He has said that what little knowledge he possessed came in part from watching Air Crash Investigation.
It is a spectacular story.
It is also a story that should immediately invite difficult questions.
Because when the actual flight profile is placed beside that narrative, we are being asked to accept an almost unbelievable coincidence of timing, instinct, aerodynamic conditions and sheer luck.
Start With the Number That Should Stop Everyone Cold
The aircraft reportedly lost more than 16,000 feet in roughly 30 seconds.
At one point, its descent reportedly approached:
544 feet per second.
That is:
32,640 feet per minute.
Approximately:
371 miles per hour vertically downward.
And remember: that was only the airplane's downward velocity.
The 737 was simultaneously traveling forward at several hundred miles per hour.
This was not a passenger noticing that an airplane was slowly descending and gently pulling the nose upward.
This was an extreme high-speed upset.
And yet the public is being asked to believe that someone who had never flown an airplane before entered that environment and made the critical recovery input successfully.
That deserves scrutiny, not applause followed by the closing of the case.
Pulling Back Isn't the Miracle. Knowing How Much to Pull Is.
Yes, virtually anyone can understand that pulling an airplane's control column backward generally commands the nose upward.
That isn't the difficult part.
The difficult part is recovering a large jet traveling hundreds of knots without killing everyone while doing it.
At those speeds, the difference between an appropriate recovery and a catastrophic one can become frighteningly small.
Pull too little and the airplane continues toward the ground.
Pull too hard and aerodynamic loading increases enormously.
Pull too rapidly and the aircraft can exceed its structural maneuvering envelope.
Increase the angle of attack sufficiently and an accelerated stall becomes possible.
Allow the airplane to accelerate excessively and overspeed becomes another problem.
An experienced airline pilot trains specifically to understand these relationships.
An untrained passenger does not.
Yet the dramatic version of this story effectively requires Hayun to have stumbled into precisely the correct solution.
Look at the Numbers
We can make a simplified calculation.
Assume the aircraft was traveling approximately 500–550 knots true airspeed during the extreme portion of the descent and following a path roughly 35–40 degrees downward.
Those aren't flight-recorder measurements. They are reasonable illustrative assumptions based on the publicly reported descent rates.
Now consider what happens when you recover.
If the aircraft transitions from roughly 35–40 degrees downward to approximately level flight over 15 seconds, a simplified constant-speed model produces roughly:
2.1–2.3 G.
That would be severe but potentially manageable.
Do it in 10 seconds and the estimate climbs toward roughly:
2.6–3.1 G.
Now we're potentially beyond the normal +2.5-G transport-category maneuvering limit benchmark.
Do it in approximately five seconds, and our simplified calculation produces something on the order of:
4–5 G.
That is an entirely different situation.
At that point we are discussing potentially severe structural loading of an airliner already experiencing an extreme high-speed upset.
And that exposes the central problem with the simplistic version of this story.
You Don't Just "Yank Back" on a 737 Doing This
If an inexperienced person saw the ground rushing toward him, the instinctive reaction would presumably be straightforward:
Pull.
Probably hard.
Possibly as hard as possible.
But at extreme speed, that could be exactly the wrong thing to do.
The faster an aircraft travels, the greater the aerodynamic forces available to produce changes in its flight path.
The successful recovery therefore requires something considerably more sophisticated than merely knowing which direction moves the nose upward.
The person at the controls needs the right input.
At the right speed.
At the right moment.
For the right amount of time.
Then that input has to be relaxed appropriately as the airplane recovers.
And according to the dramatic interpretation of this event, a man who had never flown an airplane before managed to get that combination sufficiently right while inside a cockpit that had just been the scene of a violent attack.
That is possible.
But it is an extraordinary proposition.
Consider What We Are Actually Being Asked to Believe
Forget the heroic headlines for a moment.
Strip the story down to its mechanical requirements.
An untrained passenger enters the cockpit of a Boeing 737 MAX during a catastrophic emergency.
The captain has reportedly been attacked.
The airplane is descending at a rate approaching 500 feet every second.
The aircraft may be accelerating rapidly.
The cockpit is presumably filled with warnings, confusion and physical evidence of the attack.
The passenger has never flown an airplane.
He has never recovered a jet from an upset.
He has never experienced the control forces of a 737.
He has never practiced high-speed upset recovery.
He has never trained to interpret the aircraft's primary flight display.
He has never practiced managing G-loading.
He has never practiced recognizing overspeed.
He has never practiced an accelerated-stall recovery in a transport-category jet.
Yet somehow, according to the most dramatic interpretation of the story, he reaches the controls and makes an input sufficiently strong to save the airplane—but sufficiently restrained not to catastrophically overstress it.
Think about how narrow that proposition potentially becomes.
Not too little.
Not too much.
Not too early.
Not too late.
Not held too long.
And all while the airplane is losing altitude at a rate that could consume another 5,000 feet in approximately ten seconds.
That is not merely "knowing what to do because you watched television."
That would be an astonishing convergence of instinct and luck.
And We Still Don't Know When He Actually Touched the Controls
This may be the single most important unanswered question.
At precisely what second did Hayun reach the control column?
Before the maximum descent?
At maximum descent?
During the initial recovery?
After another person had already begun recovering the aircraft?
Those scenarios are not remotely equivalent.
If he reached the controls while the aircraft was already recovering, the mystery diminishes dramatically.
If another pilot had already made the crucial input, the story changes dramatically.
If Hayun merely assisted in holding the controls while the airplane transitioned toward level flight, that is still courageous—but it is not the same as an untrained passenger independently saving a diving 737.
But if he really took over near the worst portion of a roughly 30,000-foot-per-minute descent and personally initiated the successful recovery?
Then prove it.
Because the airplane itself recorded the evidence.
The Black Box Should Be the Prosecutor's Star Witness
This isn't a mystery that has to remain dependent upon recollections made after an unimaginably traumatic event.
The aircraft's flight data recorder should contain the evidence necessary to reconstruct the critical seconds.
Investigators should be able to examine the aircraft's:
pitch attitude.
airspeed.
altitude.
vertical acceleration.
control-column inputs.
elevator response.
autopilot status.
And numerous other parameters.
Synchronize those data with the cockpit voice recorder and investigators should be able to establish a timeline.
When did the dive begin?
When did the maximum descent occur?
When did the recovery begin?
How rapidly did the aircraft pitch upward?
What was the maximum G-load?
Who was in the cockpit at that moment?
When did the qualified pilots arrive?
And most importantly:
Did Hayun actually initiate the recovery attributed to him?
Those are not unreasonable questions.
They are the questions an aviation investigation is supposed to answer.
The Aircraft Surviving Doesn't Prove the Story
There is another mistake worth avoiding.
People may reason backward:
The airplane survived.
Someone pulled it out.
Hayun says he pulled back.
Therefore Hayun must have successfully recovered it.
That isn't evidence.
The aircraft's survival actually creates another question.
If the airplane was moving at enormous speed and descending at tens of thousands of feet per minute, how gradual was the recovery?
A sufficiently smooth recovery could explain why the structure survived.
But the smoother and more carefully managed that recovery turns out to have been, the more remarkable it becomes if an entirely inexperienced person produced it.
Conversely, if the recovery was extremely abrupt, the recorded G-load becomes enormously important.
Either way, the flight recorder matters.
Courage Does Not Require Embellishment
None of this diminishes the courage required to confront an armed person aboard an airliner.
If Hayun helped subdue an attacker, that is extraordinary courage by itself.
If he entered the cockpit and attempted to help, that is extraordinary courage.
If he briefly manipulated the controls while waiting for a qualified pilot, that is extraordinary courage.
There is no need to inflate those actions into something the evidence hasn't yet demonstrated.
The problem begins when a courageous passenger becomes transformed into something resembling a self-taught airline pilot who remembered a television program and instinctively performed a successful high-speed upset recovery.
Those are very different claims.
The Story May Be True. But Right Now, the Physics Put It on Trial.
The responsible position isn't to declare the passenger a liar.
Nor is it responsible to declare the most sensational version of his story established fact.
The responsible position is to demand evidence commensurate with the claim.
Because the underlying event is already extraordinary enough.
A violent cockpit attack reportedly occurred.
A Boeing 737 MAX plunged thousands upon thousands of feet.
Passengers intervened.
Qualified pilots became involved.
And somehow the aircraft survived.
Those facts deserve serious reporting.
But the claim that an untrained passenger—whose aviation knowledge reportedly came partly from watching television—personally rescued a Boeing 737 MAX from an extreme high-speed dive is in an entirely different category.
Could it happen? Technically, yes.
Would it require extraordinary timing, favorable aerodynamic circumstances and enormous luck? Absolutely.
And until investigators release the recorder data showing exactly when the passenger took the controls, what the airplane's airspeed was, what control input occurred and what G-load followed, there is no justification for treating the most cinematic version of this story as proven.
The airplane carried the ultimate witness.
It recorded the dive.
It recorded the recovery.
It recorded the control inputs.
It recorded the G-forces.
So enough with accepting the Hollywood version simply because it makes a tremendous headline.
Release the data.
If the recorder proves that a completely inexperienced passenger stepped into a Boeing 737 MAX descending at roughly 30,000 feet per minute and executed the critical recovery without destroying the aircraft, then give him every ounce of credit he deserves.
Because that would be one of the most extraordinary pieces of improvisation and luck in modern aviation.
But if the data show that qualified pilots initiated the recovery, that the aircraft was already recovering when he reached the controls, or that his contribution was considerably smaller than the headlines suggest, then the public deserves to know that too.
Until then, there is a crucial difference between what we know happened aboard FZ1073 and what we have been told happened.
And when a story appears to require an inexperienced passenger to thread an aerodynamic needle at hundreds of miles per hour while an airliner is falling out of the sky, skepticism isn't cynicism.
It's the obvious next question.
