It happens. Ive told the story multiple times on this forum how this happened to me back in 86.
Problem with some valve, the plane would pressurize real high then suddenly depressurize. Over the course of about half the flight from Milwaukee to Memphis(?). I dont remember the aircraft jumping around elevation wise.
Caused all kinds of problems to my ears, the left one in particular is still half out a lot of times.
I’m beginning to think this 737 Max stuff is either pranks by airline maintenance people, or hate crimes by competitors of Boeing. This stuff is just too pat, too cute to be happenstance. The rule, “Follow the money trail”, fits here. Somebody is being paid to prank or disable these planes. JMHO.
Maybe Trump One its a Boeing
1. Shortages in many career fields, especially aircraft maintenance, starting in the 2008 Depression when staffing was cut and promotions were frozen. It's been exacerbated by retirements since the Scamdemic.
2. Increased cost of living in increasingly worsening areas that host airports with a lot of flights. Aircraft mechanics cannot afford to live and raise families in these areas. Some of the busiest airports are in the worst locations with the highest cost of living: JFK and LaGuardia in New York, Newark New Jersey, Chicago, Atlanta, San Francisco, Los Angeles, Boston, Minneapolis, Detroit, Seattle, Philadelphia, Washington DC, Baltimore, Nashville, etc. The second tier ones aren't much better: Portland Oregon, St. Louis, Sacramento, Oakland, Kansas City, San Antonio, Cleveland, Indianapolis, Pittsburgh, Cincinnati, Columbus OH, Milwaukee, Charleston, Albuquerque, Memphis, etc.
3. Increased Didn't Earn It (DEI) mandates for contracts. These Communist diktats are not to give women or minorities a leg up but instead give cover to lower standards of quality. It also has a self-fulfilling aspect to it - who wants to work in a failing operation?
4. Airlines are increasingly functioning like a public utility. If not for government subsidies, aircraft manufacturers would cut back, airports would close, and routes would be canceled. The government is not willing to take parts of the country off main-line as they can't afford them slipping further into the third world. It's not that they care about them, it's that they can't afford to have 3rd world outbreaks spill out into civilization.
5. The expansion of corporate jets and fractional jet ownership, increasing the numbers of passengers who previously flew first class but now fly in corporate jets. This increases the demand for pilots and mechanics for corporate jets while decreasing high-end demand for common airports and seats on common aircraft, leading to the need for more taxpayer subsidies. This also means the most discerning customers are increasingly walking away from common aircraft, airports, and routes, which leads to more acceptance of mediocrity and poor performance.
Yeah l love making stuff up and posting it. Sudden hearing loss from rapid air pressure on flights is far more common than most people know as we found out. In rare cases you can get a torn ear drum. The ear specialist said he treats people every week for air travel related hearing problems. I couldn’t give a fig if YOU believe it. I’m telling others especially if you are older use earplane plugs if you want to play it safe.
Thank you. You’re prolly correct. I oversimplified it. But all the causes you mentioned should be “equal opportunity” causes. They shouldn’t all crop up in Boeing aircraft only; or even MORE suspiciously, in the 737 planes almost exclusively. It’s just too pat; too cute. IMHO.
I wonder why these mishaps appear to be disproportionately affecting Boeing?
Interesting.
Boeing must use computers more than other airplane companies.
Otherwise, one might start to wonder if these are not just mishaps.
I suspect it's the both the nature of the maintenance contracts U.S. airlines have for Boeing aircraft compared to those for Airbus, as well as the manufacturing contracts.
That hatch that blew out on the Boeing aircraft over Portland was 100% on the Boeing subcontractor who manufactures the fuselages. The aircraft was almost brand new and the bolts were never installed. That's shoddy task performance, checklists, quality control at the hatch, and quality control on the manufacturing side where no one tracked that there were more bolts in the parts cabinets than aircraft to install them in. It's also a design flaw from the engineers because the hatch should never fit out the opening without being rotated off the Y axis and then again off the Z axis, as though you were going to take a painting off the wall, tuck it under your arm, and walk out the door with it.
Ear plugs would be a terrible idea for pressure change protection.
The air trapped between the plug and the eardrum is at normal 14.7 pressure.
If the air in your throat suddenly drops dramatically below 14.7, your eardrum will rupture inward.
I do not think you make this stuff up.
I think you do not know what you are talking about.
What is physical mechanism related to air pressure that detaches a retina?
I say that if a passenger suffers a nose bleed in flight due to loss of cabin pressure; then that passenger’s ticket should not only be refunded, but the passenger be also entitled to free round trip flight to any destination serviced by the airline.
Herodes has a theory. https://freerepublic.com/focus/news/4246224/posts?page=9#9
“The air trapped between the plug and the eardrum is at normal 14.7 pressure.”
14.7 lbs. is the pressure of air at sea level. The cabin pressure of an aircraft in cruise is the equivalent of being between 6000 to 8000 feet mean sea level.
A little knowledge can be dangerous as your post demonstrates. Earplanes are not regular earplugs they are devices specifically designed to mitigate cabin pressure. They are single use per flight. They work in tandem with an app and were recommended by the ear specialist who treated my wife.
Its not a bad theory.
Plausible for sure.
Guess its just the way the cookie crumbles. Coulda happened to any company, just happened to be ours.

The most pressurization problems I’ve had were the mid 80’s right after smoking was banned on planes. The outflow valves that control pressurization were covered with a sticky tar residue. Airlines began cleaning the outflow valves and the result was a more rapid operation of the valve causing pressurization spikes.
It took years for redesign to do away with the problem.
Today’s pressurization systems are so highly computerized and redundant that the art of manual cabin pressure control is not even taught anymore. It is even more unlikely to be taught in Korea. Heck, they can’t even fly a visual approach, ala Asiana 214 in SFO.
There are over 100,000 flights per day globally. Over half of those flights are Boeing aircraft accounting for 68% of the hours flown. Make of that what you will.
EC
Ear problems caused by flight are definitely real.
As a teenager my right ear “popped” from the pressure change and I developed an earache as our flight was landing. The pain took a good month to go away.
I’ve flown a couple dozen times since then with no problems, but it can happen.
