  1. It would have been easiest to build a conventional pedestrian bridge.

  2. Not odd at all. Why would they publicize a failure?

  3. Obviously, they did not forsee the disasterous outcome when they were designing the new models. What is hard to understand is why they did not immediately see what was wrong after the Lion Air crash and act responsibly to fix it then.

  4. Denney Pate (male) was, indeed, the Engineer of Record. He was called to account and he voluntarily relinquished his P.E. license.

  5. The one next to the canal? Maybe it will be used for the replacement bridge.

  6. This is Florida engineering, not American engineering.

  7. The problem here was design, not materials or labor.

  8. It had always been design philosophy at Boeing that the pilots had ultimate control of the aircraft. Somehow this was not adhered to when the MCAS was added to the 737. It was a major screwup, all right. Probably the culture of Boeing was degraded by the retirement of older engineers. But the irony is that Muilenburg was a Boeing engineer who worked his way up to the top. He should have known better.

  9. No, the tower was merely cosmetic. No supporting cables were planned.

  10. I was living in San José then and had driven on that structure. I now live in Oakland, about a mile from the site of the collapse. In the aftermath, the Dept. of Transportation reinforced the supports of elevated roadways all around the area.

  11. Rushing wasn’t the problem. It was fundamentally a bad design.
    1
  12. Not a factor.

  13. When I lived in the Twin Cities I always understood the “W” and “E” as West and East. It didn’t matter how you referred to it, nobody would think you meant direction of travel.

  14. There was a lot of finger-pointing after this incident. Every group wants somebody else to pay for improvements, so nothing gets done. The project gets more expensive and takes longer by insisting on a total solution, with approach improvements and gates. My opinion is that the county could have improved the safety of the crossing greatly by building approaches that crossed the tracks at right angles, and that provided enough level space for trucks and farm equipment. They should not have needed partners to do this. Still, the truck driver was most responsible.

  15. AvE resorted to speculation and called it wrong in some respects. If you want the facts, read the OSHA report and the NTSB report.

  16. That money is to do the work, though. It isn’t all profit.
    1
  17. The number of trusses was not the problem. The whole concept was unsound.

  18. The A330 had a similar incident (Qantas 72). It didn’t get much attention in the United States because it wasn’t our airplane and it wasn’t our airline.

  19. There are others who deserve some of the blame, beginning with FIU.

  20.  @peteconrad2077  — With MCAS active, the handling is supposed to be similar to the NG models.

  21. It wouldn’t be murder unless you could prove that they intended that their airplanes would kill people. That doesn’t make any sense. The MCAS was incompetently designed, but that doesn’t make it murder.

  22. All 737s have two AoA sensors.
    1
  23. The appearance wasn’t for the students who would use it, it was for the FIU promotional materials.

  24. The weakness in your argument is that the company’s own website uses “FIGG.”

  25. The university did not design the bridge in detail, but they wanted a bridge that would make a bold statement. They certainly were involved in developing the concept. It could not have been built without their approval of the concept.
    1
  26. It was doomed, but AvE was not a reliable source of information generally. They speculated and were wrong about some key matters.
    1
  27. The highway was there first.
    1
  28. The Engineer of Record is known. The President of FIU is known. The companies involved are known. It isn’t known who contributed what to the design of the bridge. No one would claim credit for the concept.j

  29. Doctor Whosit — They were replaced.

  30. Airbus has also had incidents. Qantas flight 72 was particularly bad, although a highly skilled captain was able to save the plane. The A330 should have been grounded after that, but I don’t think it was. The world barely noticed and the problem, similar to that in the B737 MAX, was fixed quietly.

  31. We (in the USA) are not all the same, but even highly skilled pilots, with a reputation of being conservative in how they handle the aircraft, can sometimes get into a situation from which there is no escape. Recently, a B-52H went into the water near Guam, apparently from stabilizer trim being out of control. The crash was not due to arrogance, but may have been due to an error in judgment, and of failure to recognize the problem and take corrective action soon enough. A MAX crash certainly could have happened with a US pilot. When things go wrong in unexpected ways, the crew may or may not get out of it, depending on decisions they make on the spur of the moment, regardless of national origin.

  32. It was not a stress test. The road should have been closed, though. Even earlier.

  33. Consider, though, that the airlines wanted to avoid the training costs. Boeing just wanted to sell airplanes.

  34. “Tail mounted engines”? The 737 has always had engines mounted below the wings. Early concept drawings of a plane with rear-mounted engines have nothing to do with the 737. The differences in engine type and location, and fuselage length, have nothing to with the two MAX crashes.

  35. “Munilla” was the name of the owners.

  36. This bridge was Florida made. It is not representative of US bridge engineering.
    1
  37. There is a new design which will be built.
    1
  38. Not correct.

  39. Ukraine started that war by trying to extirpate the Russian-speaking Ukranians in the east. The West should have stayed out of it.

  40. The MAX is similar to, but not exactly the same plane as the NG-series. I don’t know what mean by “the same plane,” though.

  41. Architects work with structural engineers when building complex structures. In this case, the engineers didn’t do their job properly.

  42. I’ve seen the video, but this incident is so old and so well documented that it is not worth revisiting.
    1
  43. That has been discussed in other places, however there are two nations in Major League Baseball, so it is an international sport.

  44. There is nothing wrong in principle with using software to help fly the aircraft. They just botched it.
    1
  45. The highway was there first.
    1
  46. FIU did not do the detailed design, but they originated the concept.
    1
  47. The recertified MAX has never had a crash. It is as safe as any commercial aircraft flying. I have no qualms about flying on it and have flown on it.
    1
  48. The Engineer of Record said that. He relinquished his license voluntarily.
    1
  49. AvE was wrong on some important points. The main thing that would have avoided it would have been a conventional design using steel trusses.
    1
  50. You mean 737 MAX 8.
