737-800 down in China

Why has this not been on the news? I watch breakfast news before work and I've not heard anything about this on there. Just seems a bit odd to me.

Nothing new to say until the investigators report with their findings and other news would push it down the priority list. They'd just be running pictures of grieving relatives which is just tacky.

It could be weeks or months before the reports come out.

As it was on descent and may not have been fuelled up for further flights it could have been on the low side but enough for the flight. It clearly didn’t have as much as other crashes as there is very little charring.

What I've described is basically the minimum that any aircraft carries which is enough for some go arounds and a diversion. There's no way the tanks would be even getting close to empty.
 
Reading just now that they reckon it hit the deck at nearly mach 1.
They then followed this with no survivors had yet been found...
I'd be surprised if they found any part of someone bigger than a thumb with the forces involved.

For clarification purposes here are the rules on fueling. Though I have heard that some cheap airlines push the limits with regards to restricting the amount they carry for cost purposes.

Per ICAO Annex 6, Part I, section 4.3.6 "Fuel Requirements," airplanes should calculate their required fuel quantity as follows (summary; see below for actual ICAO text):

  • Taxi fuel
  • Trip fuel (to reach intended destination)
  • Contingency fuel (higher of 5% of "trip fuel" or 5 minutes of holding flight)
  • Destination alternate fuel (to fly a missed and reach an alternate)
  • Final reserve fuel (45 minutes of holding flight for reciprocating engines, 30 minutes for jets)
  • Additional fuel (if needed to guarantee ability to reach an alternate with an engine failure or at lower altitude due to a pressurization loss)
  • Discretionary fuel (if the pilot in command wants it)

So that pretty much justifies what I've said, probably meaning there's more in the tanks than I actually suggested.

(I've spent many hours working out fuel planning in the past, admittedly in a sim but using real world procedures).

It's just been announced on the wireless that one of the black boxes has been found.
 
What i don't get is how it dropped from an alt of 29,000 straight down, even on approach Autopilot is on you would have contact with ATC with heading, speed and alt. I can only assume that ATC requested them to change Altitude and change the Vertical Speed and descent and something went CLUNK.

With the loss of control autopilot will have switched off and given control to the pilot. Something happened when the descent was initiated that caused the loss of control. For example a spoiler only lifted on one side. That can be enough to catch out an inexperienced pilot. That would fairly quickly flip the aircraft over.
 
Could be the elevator controls as this would control the pitch of the aircraft. Be interesting to see what the maintenance was on the aircraft and if there was mechanical issues with the tailplane. It does seem that at 8000 feet they regained some control before it dropped again which makes it seem that there was some rudder / elevation issues.

This could finish Boeing if it was found out to be the plane.

You mean like how they were finished when two of their best selling planes in history killed 300 people and they totally lied about it in terms of air worthiness and required pilot training? Then blamed 3rd world country pilots for being incompetent?

Oh wait...

That's what I mean. You can get away with it once but to happen again on different plane could be disastrous.
 
I don't think it's boeing that are the issue, it could be there was missed maintenance on the tail plane or ailerons. There is some other speculation that there was a power outage but if that was the case it would be impossible recover even at 8000 feet when they seemed to have some control of it for a small amount of time.

Also they would just switch to APU
