  1. Not as much as they once did.

  2. No, those cargo doors had a poorly designed latch. That isn’t the case here.

  3. Gun controls are also placed on a yoke, such as in the Beaufighter.

  4. The landing gear was modified for the -10 for slightly greater height. There is a limit to what can be done without major alterations to the airframe. Besides, that's not the whole cause of the problem.

  5. If Boeing leaves the commercial airplane business, their market share will be taken over by China. Does that sound like an improvement?

  6. Musk is a cult figure and posts like this prove it. Cults are not the answer.

  7. good point

  8. This was an aberration.

  9. No, it was Montreal to Edmonton.

  10. Who cares what Musk says?

  11. It isn’t possible to fall out if it is assembled properly. Because the door plugs a doorway that is designed for a functioning emergency exit door, it uses the retention system that was designed for that purpose.

  13. They did redesign it for the -10, but that doesn't change the effect that MCAS addresses. It's a small lift because the new gear has to fit in the space of the old gear. The greater takeoff thrust of the new engines causes a greater pitch up moment, so more trim is needed to compensate.

  14. That would be disasterous.

  15. As do we all.

  16. It’s a test flight. That is an instrument to measure air pressure.

  17. I don't think he has an anti-Boeing bias, and I have watched all his videos on the 737 MAX problems. This video is accurate.

  18. There is nothing wrong with the engines. They are not related to this incident.

  19. Yes, but how can a runway with snow on it be dry?

  20. I like B737s. I don't fly on them as often as I once did, though.

  21. A lot of thought was put into the revisions. It is only used during takeoff, so one trim adjustment is sufficient. It isn't necessary at all, from a flying standpoint.

  22. Recall that Muilenburg, who almost killed Boeing, came up out of Boeing engineering.

  23. The recertified MAX has a perfect record. The version that crashed twice was an aberration, and it’s gone.

  25. Muilenburg had an engineering degree.

  26. The irony is that when something goes seriously wrong (as it did), it costs a huge amount of money.

  27. This is an excellent overview of the big picture. I have have followed this story from the beginning. My view is as a career software engineer (now retired), who worked mainly on low-level software. The fundamental cause has always seemed to me to be the botched MCAS design and implementation. I don't understand how they could use only one AoA sensor to make a decision resulting in hidden control inputs, and to let it run away was a critical error. I think that part was an oversight — the scenario probably was overlooked. It resulted in a system which broke Boeing's long-held policy that the pilot is in ultimate control of the aircraft. I do have one question about the stab trim shutoff which I have asked before but no one has answered. It seems that the shutoff switches block not only trim inputs from the computer, but also trim inputs from the switches on the yokes, leaving only fully manual operation from those wheels. That seems to be an impractical way to retrim the aircraft in a hurry, especially when it is badly out of trim. Why not shut off the automatic trim, but leave the pilot with powered manual trim?

  28. Boeing is right about the certification exemption, in my opinion. The Congress want to impose changes on what are mere variants of an existing, certified aircraft. It is better that all variants of an aircraft type work the same way, except as necessary.

  29. Greater thrust was probably the principal factor.

  30. Boeing Commercial Airplanes is what we are concerned with here.

  31. The tire measurements are not "inexcusably complicated." They aren't even complicated. The size is rim diameter, width, and profile (aspect ratio). You might have to look up speed and wear ratings. Most people just replace tires with the size they have already. Those who change size are able to figure it out.

  32. A nautical mile is 15% longer than a statute mile.

  33. Muilenburg was an engineer.

  34. Delays in manned space flight are not unusual. I don’t want them rushing the program.
    1
  35. Muilenburg was a Boeing engineer who became CEO, and his handling of the MAX crashes was horrible.

  36. The MAX is the fourth generation. Every generation contains revisions, so it is not the same aircraft as the first generation. The type has survived because airlines buy it. Boeing would not have made another generation if their customers had not been ready to buy it.

  37. Isn’t it also thievery to impound assets of Russians? It seems to me a natural response. When the war is settled and the sanctions lifted, then the disposition of the aircraft can be worked out amicably.

  38. The four bolts that are being discussed are the pins which keep the plug door in place.

  39. They were destined for a Russian airline, but never delivered. I think it was a good plan to use these as the base for the next presidentual aircraft. As for cost overruns, there are some factors which are not related to the fact that they had been fitted out for an airline. It doesn't cost much to take out the interior. The custom work needed for a presidential airplane is where the cost is. I expect they will fine when they are delivered.

  40. There is nothing wrong with the airframe. It has lasted so long because it’s a good airframe. As for your “deathtrap” charge, the recertified MAX has had no crashes at all. By that measure it is the safest aircraft flying.

  41. The good news is they are sticking with the classic livery, and the 747 will be flying for another 30 years.

  42. The Wi-Fi installer has denied doing any work involving the doors. The NTSB will figure out who worked on the door.

  43. You are not required to listen.

  44. In my opinion, it is poor policy to treat a new variant of an existing aircraft in the same way as an entirely new aircraft. It is better that al varients of an airplane type have commonality.

  45. Boeing’s biggest customers influence what Boeing builds.

  46. Boeing certainly mismanaged the whole business by trying to bully Bombardier.

  47. You skip 3/4” square drive?

  48. The seats were sold but there were two no-shows.

  49. The reason there have been many 737 crashes is that there have been a huge number of 737s built and placed in service. Many crashes are due to pilot error or weather, and not any defect in the aircraft.
