  1. I did not imply that the bird was badly designed, but to point out that the 737 engine placement was not the root cause for its problems. In the past, we have engine(s) mounted in the tail, nose, above the wings and in back of the cockpit and none had stability problems.
  2. I did see something interesting, the engines.... They are huge! something like 11 feet in diameter and they are mounted ahead of the wings, not underneath, similar to the new 737...
  3. My father had an ongoing war with Gophers. He would spend hours watering the hole, only to have the gopher exit from another hole. Finally he used Carbide. He would put it in the hole, add water, and the carbide gas that was heavier than air would sink to the bottom, then one match, and it was the same results as the vid. But he never got rid of the gophers....
  4. My Ti Wifes home is Amanat Charoen where she is building her retirement house. I am amazed how the area has changed over the last 15 years from a small rice village to urban.
  5. Interesting, you in Ubon? My Thai wife is from close to Ubon and we are building a house there.
  6. An interesting opinion with almost no facts.
  7. Ok so what? I pointed out that when you mount engines on the tail it effects the CG much more, and of course when you mount engines on the front, its the same.
  8. This is old news and doesn't make sense to me. Aircraft engines have been mounted in the wing, on the wing, over the wing, on the tail. on the front etc.
  9. I agree that none of that helps Boeing, but to say that the test rocket malfunction is taking Boeing down is a streach.
  10. Come on, a malfunction of a test rocket is taking Boeing downhill? What a load of BS.
  11. I never tried to walk either on the beach or the road to Pattaya, as I would walk south on Jomtiem beach road.
  12. When I lived in Jomtiem, I too, did not go to the beach, but I enjoyed every morning the walk up an d down the beach on the nice sidewalks.
  13. Its much more than just "small" planes. It is new materials, new engines etc.
  14. That statement ignores economic life. The bird is not able to compete with other birds. Pretty simple to understand whey they only built 300+ and are scrapping them.
  15. That sort of things happen all the time - A Manufacturer will issue a advisory and the Airlines will inspect what was advised.
  16. Yes, and Aloha is out of business and Hawaiian is still flying the DC-9's, even though they had to get a waiver from the DOT as they dont pass the latest noise rules and other things. Southwest is just putting its toe in the water here in Hawaii and is starting to fly interisland as well as mainland flights and of course, they use &37's....
  17. 99% of the interisland flights here in Hawaii use 717 (DC-9) So I use them frequently - Not my favorite bird, but I have no choice.
  18. Yes, it's the same bird as Boeing acquired it when they Bought MD and let the production die. As for ground clearance, the DC-9 had tail mounted engines that were mounted on the fuselage so even if they upgraded the engines ground clearance would not be the problem, but production stopped before bigger diameter engines became available. Southwest Airlines ONLY flies 737's and they insisted on the Max to keep the same ground height as all of the infrastructure they have was designed for 737's and any new height would require a massive change and investment.
  19. To me,the reason for 3 holers went away is the same reasons that 4 holers are also going away - They are too expensive to fly. The 2 hole DC-( ( Boeing 717) is still flying here in Hwaaii and it has 2 read mounted engines with a great safety record.
  20. I too know nothing about aeronautical engineering - I was a EE major, but I do have knowledge as a pilot. No fixed wing bird I have ever flown was unstable and from what I understand none of the ones I mentioned were unstable as long as you keep within the approved W&B. To me a stable bird is one that is trimmed for cruze straight and level and you pull up and twist the stick, then let go, the bird will return to straight and level.
  21. i read that opinion piece and its the usual more lift with the engines a foot or two forward of the CG, but they never mention how much extra lift is generated. My guess is very little and that can be offset b y other changes. Lots of jets have engines mounted in the tail, which is much farther away from the CG than the 737, but no one is saying that creates unstable downward lift and is unstable.
  22. Sounds like pure BS to me. From what I read, SW airlines, who is the biggest customer of Boeing's narrow body tubes, insisted on the same low tube height so all of its ground infrastructure could be used on it. To do that, they had to mount the bigger diameter engines a few feet forwardard, changing the W&B a bit, but that does not make it unstable. They did come up with a hairbrained solution - MCAS that relied on a single pitot tube to tell it when it was about to stall and when that failed, they did not tell the carriers how to disable it when it failed. Any sane pilot can tell by the seat of his pants when a bird is close to stalling, and they have multiple instruments that also give a true airspeed reading, some requiring zero power. I have many flight hours in birds with NO electrical power.
  23. Lots of blame to go around. The crew did not have a clue how to deactivate the MCAS system and spent precious seconds trying to figure it out, resulting in the crash. Bad design and lack of training IMHO.
