I noticed that; maybe was in a stall (although 80 seconds) and after gaining enough speed was able to pull out, it also looks like it was level for a few seconds so maybe there was structural damage in pulling out. Too much rudder, tail falls off or just severe damage to other structural parts of the fuselage, wings etc meant recovery was not a realistic outcome. It's all speculation though and I don't really like speculation so willl be interesting to see the first reports, hope also they get the CVR and FDR which will shed light on what took place.

Reports are the plane was traveling around 350 mph on impact, so an 80kg person... well let's just say there probably isn't much left of the person on impact. RIP to the 132 souls on the flight. 1 1 Link to comment Share on other sites More sharing options...
forcebwithu Posted March 23, 2022 Share Posted March 23, 2022 They're still searching for the flight recorders, which got me to wondering if they will have survived the crash. According to this article What Would It Take To Destroy A Black Box? Quote The black box must be able to withstand an acceleration of 3,400 Gs (3,400 times the force of gravity), which equals an impact velocity of about 310 mph. It must also survive flames up to 2,000 degrees F for one hour, and the beacon should be able to emit a signal once per second while submersed in 20,000 feet of saltwater for 30 days. Don't know why the Car Crash Calculator I posted earlier comes up with a much higher G-force than the one cited in the article for a plane traveling at 310mph, but reports of MU5735 impacting at 350mph means it's possible the data on the recorder may not have survived the crash either. Hope that's not the case. 1 Link to comment Share on other sites More sharing options...

The altitude reading is calculated from a barometric pressure. This pressure can allegedly do strange things when an aircraft is flying out of control, and especially so if breaking the sound barrier as apparently happened here. Regarding the black box operational requirements, even if they are exceeded and it malfunctions, the memory devices inside have further protection and may be readable after recovery from the broken unit. 1 1 1 2 Link to comment Share on other sites More sharing options...

Flightradar uses ADS-B data which comprises much more than radar only derived data. Quote ADS-B Out works by broadcasting information about an aircraft's GPS location, altitude, ground speed and other data to ground stations and other aircraft, once per second. Air traffic controllers and properly equipped aircraft can immediately receive this information. This offers more precise tracking of aircraft compared to radar technology, which sweeps for position information every 5 to 12 seconds.

Sea-Hawks Posted March 27, 2022 Share Posted March 27, 2022 When I was working in Thailand, I worked quite a bit in China and took China Eastern Airlines many times. After the chaos and all the pushing and shoving that goes on while boarding and disembarking along with the dirty acts on the plane, chose not to fly China Eastern Airlines whenever I could use another airlines. I don't have any good things to say about CEA or some of the etiquette of Chinese from China. 2 Link to comment Share on other sites More sharing options...

bob lt Posted March 31, 2022 Share Posted March 31, 2022 (edited) 2 days should be ample time to replace the data in the black box. Wouldn't it be standard practice for either representatives from the NTSB or Boeing to be present? Edited March 31, 2022 by bob lt 1 Link to comment Share on other sites More sharing options...

tom72 Posted May 17, 2022 Share Posted May 17, 2022 they do not want to say what happened by the looks of it. when it first happened it looked like it lost cabin pressure then rapidly lost altitude as it is supposed to do then tried to correct itself then it went straight down. 1 Link to comment Share on other sites More sharing options...

Golfingboy Posted May 20, 2022 Author Share Posted May 20, 2022 I would never trust China to tell us the whole truth, but at the same time this could be “fake news”. It looks like the different US headlines all quite the same source. Whatever the cause, I could not imagine the horror they felt those final seconds.
