Whether or not the MCAS is to blame, remains to be seen. Fact is, that someone at Boeing RIGHT NOW is saying to himself: “I sure hope that the MCAS has nothing to do with it...!” What a tragedy. |

It's absurd that flight telemetry and data is not transmitted in real time to satellites and sent back to the aircraft manufacturer.rather than being recorded on FDRs that are lost at sea or destroyed
And now back to your flight simulator. |
MRyan GANZIC..
Thank you for that. Much appreciated. |
"Captain asked to return" .... also same as JT610.

Given the MCAS software update was delayed ubtil after Apr... this seems to point to a MCAS issue |
I bet boeing are there big time. Will wait for report of course. RIP paxs and crew.

More rubbish than usual on this one. Ethiopian have a poor safety record for an airline its size. That is clear. And colleagues who fly for them have privately expressed concern about many safety-related issues at the airline. No details to share.
No conclusions can be drawn until the CVR and FDR are recovered and their contents analysed. |

Fact is, that someone at Boeing RIGHT NOW is saying to himself: “I sure hope that the MCAS has nothing to do with it...!” And I still have to question the engineers who created MCAS. I can understand MCAS as a cheap (and semi-back-door) stick pusher system. It is far from ideal, but is a software change rather than a complete new system. Money rules, and MCAS was a cheap and simple fix.... However, I do have to question the logic of a pseudo-stick-push that keeps operating until you get full forward trim. Have you tried this MCAS-trim-runaway in the sim? According to the sim, the aircraft is only just about controllable with two gorillas hauling back on the stick (about 40 kg pressure on each stick). And that was in level flight with the CofG in the central position. Ok, now try a recovery from a stall-dive, with a forward CofG, 20º nose down pitch, and speed rapidly building back up to 250 kt. Absolutely impossible - you are doomed. And doomed by an anti-stall system that is supposed to save you. But who in the world would want to recover from a stall with the trim-stabiliser set fully forward? The stabiliser is more powerful than the elevator. Heck, even the Wright Brothers knew not to do something like that. And I also have to question an aircraft that has not been designed by anyone. The 737 was designed for the 727 (or 707) back in the 50s (the type-certificate is 1967), but since that time there has been mod after mod after mod. Never going back to basics, but simply a series of mods upon mods. It is like driving a Model-T Ford, with a new 300 hp engine and a new dashboard. For instance, the 737 is still the only aircraft I have flown, where the controls cannot be split if there is a control jam. And still it flies... Silver |

If that earlier picture shows the main crash site I wonder if there is anything left of the FDRs.

Event: The U.S. Embassy is aware of calls for a protest to be held on Sunday, March 10, 2019 at Meskel Square. It is unknown whether the protest has been or will be approved by Ethiopian authorities. Protests have already occurred in many parts of the Oromia region since March 6, and additional protests may materialize.U.S. Embassy personnel are advised to avoid Meskel Square and limit movement around Addis Ababa on Sunday, March 10. U.S. Government travelers have been advised not to arrive or depart Bole International Airport on Sunday, March 10, and U.S. Embassy personnel are also temporarily prohibited from traveling to Oromia.Actions to Take:
U.S. Embassy Addis Ababa, Ethiopia +251-111-306-000 Also: Eyewitness: The blast and fire were so strong https://www.bbc.com/news/live/world-africa-47513534Our colleague Jibat Tamirat from BBC Amharic has just spoken with a man, Bekele Gutema, who says he was near the crash site around the town of Bishoftu, which is 60km (37 miles) south-east of the capital.He says: "The blast and the fire were so strong that we couldn’t get near it. Everything is burnt down. The firefighters arrived around 11 and the crash happened around 8. There are four helicopters at the scene now. No one will survive." |

We have no ideas beyond some possibly educated guess-work as to what happened here but I do have a question that can be answered by someone with the relevant experience. As a 10,000 + hr career pilot I'm not exactly a newby but have not any experience with the latest sophisticated systems being introduced on modern aircraft.
Q. Is there something preventing pilots of these aircraft from simply hitting a 'disconnect' button, listening for the 'C' tone and then getting on with flying manually ? Not suggesting that this is relevant to this accident. |

This is only the second 737 Max accidents since the aircraft was launched, so it is premature to be calling for its grounding.
To wit, a brand new derivative of a 50-year old design, engineered and built by one of the two premier commercial airframe manufacturers, should not have suffered two crashes within such a short time-span. Particularly not if the first may have had a questionable piece of software, relying on a single sensor input, as a major contributing factor. If this, second, accident is in any way linked to the first by a common failure, the only prudent cause of action will be to ground the fleet and allow the manufacturer to get things straightened out. |

The U.S. government sends these email/twitter alerts out to U.S. citizens almost as often as Nigerian Princes ask for help in recovering lost money. I get about 20-30 of these alerts every year in Copenhagen.

A very sad day for Ethiopian Airlines. My grandfather was the very first Flight Surgeon and Chief Medical Officer of Ethiopian Airlines. I've personally been flying them since 1976. And it's my go to airline when flying to/from or in Africa. So all the way from Austin, TX, this one hits close to home.

Looking at the crash site, there is virtually nothing left.
Compare this with the MH17 crash site, shot down from 33,000 feet. |
Boeing will be hit hard by this accident, regardless of the issue that caused it, all news agencies already speculating just as bad as ppruners here.

Oh puh lease which planet are you on? Ethiopian has always been a very professional airline with an excellent safety record and mostly excellent service and reliability. They were managed by TWA during the 60s and 70s and have always kept their professionalism intact. I find your comments offensive.
