As I've said before the plan traveled at a speed of 360 kilometers an hour. That's literally engines off, nose down! So am i right in thinking that you believe that 360kph is a reasonable speed for an aircraft with no engine power in a vertical dive? If so I'm not going to argue with you. In fact I'll even offer you a possible explanation. One of the pilots spooled down the engines and put the aircraft into a vertical dive, That's literally engines off, nose down!

So, yeah blame it on the American plane. The plane (737-800) that crashed in China is not the same one that had the two crashes (737 Max) that required the plane to be taken off the market. Will the plane black box remain in China ? 2 Link to comment Share on other sites More sharing options...
Isaan sailor Posted March 26, 2022 Share Posted March 26, 2022 Almost 22.000 ft decent in 72 seconds. And a witness (unverified) saw a plane heading nose down. Doesn’t look like a mid-air breakup. Link to comment Share on other sites More sharing options...

It's essentially the max speed a plane can reach by just falling nose down straight out of the sky, which makes me think engines failure, but it's definitely not being massively overspeed. I dropped vertically in the mountain . Vertically means massive overspeed . Engine failure does not lead to vertical crash , unless pilot error . A airplane can fly from 8km high without any engine pretty far and land without problem . skip to 1:21 and you see the security cam recording the plane falling vertically from the sky . There are not many reasons to do so . 1 of them is serious pilot error , 2nd big reason is the tail section ( horizontal stabilizer ) being gone for 1 reason or another . And actually not many other reasons are there , 1 Link to comment Share on other sites More sharing options...

And actually not many other reasons are I don't get your point. This type of aircraft has a max speed of 946km/h. It crashed with about 360 km/h, so there's no way the engines were oversped during the free fall. Going nose down is not the definition of being overspeed. Overspeeding in a jet plane means the turbine rotates so fast that it exceeds the structural integrity and then the engine disintegrates. The maximum velocity a jet plane can reach with its engine/ engines will always be much greater than the terminal velocity a plan can reach by falling out of the sky.

The speed measured in Flightradar is horizontal ground speed , not speed in general . Even the horizontal ground speed exceeded the max of 540mph ( 590mph) .

Even the horizontal ground speed exceeded the max of 540mph ( 590mph) . Wrong Sezza! The speed shown on Flighttracker is airspeed, in knots, as measured by the pitot/static system of the aircraft and relayed, by telemetry to FT. Ground speed is a measurement of the aircraft's progress over the ground and is not always the same as airspeed. During the aircraft's final decent, the 'groundspeed' would in fact have been just about zero. When the aircraft pitched down it began to increase in speed. No surprise there, it was trading lift for speed and thus accelerating. It reached a terminal velocity of 590kn at 7,850ft and then began to slow down again as it came into denser air. Impact speed was 370kn Link to comment Share on other sites More sharing options...

stratocaster Posted March 27, 2022 Share Posted March 27, 2022 There have previously been three proven similar accident scenarios involving 737's. Hijacker entered cockpit and shot pilot and co-pilot Short circuit in wiring harness caused thrust reversers to deploy in mid flight. A wrongly assembled elevater servo motor jammed in the maximum nose down position. A major safety concern with the 737 class is that it still uses steel cables to activate the control surface hydraulic servo motors. Even the 737 max. This is termed a single point failure and is one of the few commercial aircraft to be certified with such. To refit the class with a two point of failure system ie. fly by wire, or double cable would have involved re certificating the fuselage. Link to comment Share on other sites More sharing options...

Stargeezr Posted March 27, 2022 Share Posted March 27, 2022 Considering there was no communications from this jet liner, makes me think that something serious happened to knock out the ability for the pilots to communicate. I do hope that the flight data recorder will give good data. If a voice recorder is also located at the tail end of the aircraft, then we may get some date. It sounded like the one black box they found was very damaged, so hope they can still get the data. It was a tragic crash. Link to comment Share on other sites More sharing options...

I already suspected that this latest incident was a deliberate act and that glitch in the dive does give my suspicion some credence.
