Boeing 737 MAX 8 ET 302 registration ET-AVJ from Addis Ababa (Ethiopia) to Nairobi (Kenya) with 149 passengers and 8 crew, was lost 10 March 2019 shortly after takeoff at 08:44L (05:44Z). There were no survivors.

Boeing 737 MAX 8 registration ET-AVJ performing flight ET-302 from Addis Ababa (Ethiopia) to Nairobi (Kenya) with 149 passengers and 8 crew, departed Addis Ababa's runway 07R and was climbing out of Addis Ababa when the aircraft levelled off at about 9000 feet MSL, radar contact was lost shortly after at 08:44L (05:44Z). The aircraft wreckage was found near Ejere at approximate position N8.8772 E39.2512. No survivors were found.

In a subsequent press conference on Mar 10th 2019 Ethiopian Airlines reported the crew reported difficulties and requested a return to Addis Ababa. The captain was with Ethiopian Airlines for 9 years and had about 8000 hours of flight experience, a first officer with 200 flight hours assisted, there were 35 nationalities amongst the 149 passengers. The crash site appears to be consistent with a steep dive, the aircraft is right inside the ground. The aircraft had undergone last "rigorous first check maintenance" on Feb 4th 2019. The aircraft had last operated to and from Johannesburg (South Africa) arriving back in Addis Ababa in the morning of Mar 10th 2019 before departing for the accident flight.

Link to Aviation Herald discussion.
The incident appeared similar to the 29 October 2018 crash of Lion Air 610, operated by a B38M.

Indonesian carrier Lion Air Flight 610 on October 29 crashed into the sea soon after takeoff with the loss of all aboard, apparently due to the erroneous data from a faulty Angle of Attack sensor, which caused the MCAS (Maneuvering Characteristics Augmentation System) to assume the plane was about to stall, which activated the downward force on the Stabilizer Trim to get the nose down. Link to BBC article.

This aircraft had been written up as having a faulty AOA indicator for previous flights it had taken. It is unclear if Lion Air had performed adequate maintenance procedures after the reports or withdraw the aircraft from service until the fault could be completely cleared.

Link to Aviation Herald discussion.

“Instead of switching off the Stabilizer Trim the pilots appear to have battled the system.” Link
Boeing 737 MAX and MCAS: See “What is the Boeing 737 MAX Maneuvering Characteristics Augmentation System?”, updated November 17 to explain the MCAS and electric trim override operation, here: link.

Boeing has stated a revised MCAS is in the works, and the FAA is expected to issue an AD note when the MCAS update is done. This is expected to occur in early April, 2019.

355 B38M deliveries have been carried out through 1 March 2019, out of 5,123 orders. Link to Wikipedia B38M list of Airlines, orders and deliveries.

Ethiopian Airlines is the flag carrier of Ethiopia, and commenced operations on 8 April 1946, expanding to international flights in 1951. The firm became a share company in 1965 and changed its name from Ethiopian Air Lines to Ethiopian Airlines. The airline has been a member of the International Air Transport Association since 1959 and of the African Airlines Association (AFRAA) since 1968. Ethiopian is a Star Alliance member, having joined in December 2011.

As of November 2017, the carrier served 105 international and 20 domestic passenger destinations and 44 cargo destinations. Ethiopian serves more destinations in Africa than any other airline. Ethiopian Airlines’ fleet consists of 106 aircraft.

Horrible! I arrived in Addis two days ago on same plane type.
​​​​I am writing this from Addis Ababa where there is clear blue sky and no mentionable wind. Certainly sounds odd that a plane would just fall out of the sky in these conditions?

Let us know the flight no and date, and we can look up the scheduled aircraft type for you. However ET often change aircraft type in the week leading up to the flight.

Geoffrey Thomas, the editor in chief of Airline Ratings, told CNN the Ethiopian Airlines crash on Sunday had "significant differences" to the Lion Air crash last year. On the Lion Air flight, there were "wild fluctuations in air speed and... we continued to get data from the plane all the way down to impact."
I'm surely seeing those wild fluctuations in the vertical speed

The Aviation Safety Network has more information regarding the crash and the plane itself.

Normally you can see the aircraft type by clicking on the flight number during the online booking process on the airline's website. Otherwise, there are multiple other options including seatguru.

It appears this flight had problems climbing, and after 6 minutes was only at 1000' above the airport -- which is surrounded by mountains, so it almost certainly slammed into a mountain.

The question I guess is why they didn't try turning back?

Isn't it more likely the pilots correctly responded to incorrect airspeed data?

Drawing conclusions based on data from amateur websites in the immediate aftermath of an incident is not a good idea, neither is speculation about airspeed (which such sites do not show anyway, btw)
Speculating on anything right now is utterly pointless - especially "slammed into a mountain". Geez.

I'm sorry, I disagree. There is at least the appearance of some similarities between JT610 and ET302 and one should be able to discuss this.
If discreet speculation is not allowed then this is basically a condolence register. I'm 100% sure everyone here feels extremely sorry for all those lives lost, as well as their families going through absolute hell.
