Looking more likely IF reports are to be believed that transponder pings appear to be coming from further out to sea than the known debris field, indicating an inflight separation of the stabilizer which is of course catastrophic and unrecoverable.


It also doesn't really say that the in-flight separation is the cause of the accident. As the plane was out of control, it could have exceeded its mechanical limits and then broke up, or it could have hit the water and broken up while cartwheeling, flinging pieces farther downrange than the bulk of the fuselage.

After sinking, if the pieces containing the beacons were small enough, they may have been swept out by the currents or tides afterwords, too.

I didn't see the report you were mentioning, so I don't know how much farther out to sea one of these beacons are.

Boeing has only 78 undelivered B737-800 models left. If it has to stop delivering the B737 Max while an investigation is being conducted they can switch to the B738 for about three months, and then that is finished.

Someone recently commented that once you integrate engines, instruments, control surfaces and software, you get a type of safety that is reassuringly deceptive because whatever fails will be something new and different and untrained for.


If it was a pitot cover or pitot device then intermittent data of poor quality can confuse the computer's response but the pilots should ignore rather than worry about the misinformation given the perfect flying weather and proximity to the airport.

Various sources confirm recovery of 'an orange object' or 'a black box'. No indication of whether it is FDR or CVR. Diver quoted as 'we dug for it' indicating mud and debris near a pipeline and strong currents.

Reuters reports it is the FDR rather than the CVR.

I would think that with the advances in modern technology, they should be able to put the functionality of each box into both boxes.

When you look at the number of everyday items that simply float to the surface, you would think that black box recorders would be better off with a redundancy of 5 or 6 times. Some would be designed to be lightweight that could float to the surface while others would be heavy and in armored containers. The investigators might get lucky and find one of the lightweight copies and keep on diving for the armored variants.

Quite some time ago a video was posted of a Pushback, Taxi, Takeoff and initial climb out of a Malay Air jet at Brisbane airport all taking place with three bright red Remove Before Flight streamers flapping in the breeze.

Boeing issues advisory, FAA to make it mandatory change in manuals for erroneous Angle of Attack indicators.
Previous four flights had been with erroneous aoa indicators.

CVR not located. Search continuing.
