PLEASE READ BEFORE POSTING
If you are new to us, welcome to FlyerTalk!
Who we are: FlyerTalk features discussions and chat boards that covers the most up-to-date traveler information; an interactive community dedicated to the topic of travel (not politics or arguments about politics or religion, etc.)
All travelers are welcome in the community. Just choose a forum: conversing about airlines and their programs, airports, destinations, dining and how to make the most of your miles and points, or visit our Information Desk to start.
We do have some Rules, and everyone agrees to abide by these when they are granted free membership privileges. On a topic that generates a lot of feelings and perspectives, please remember "welcoming, respectful" are key words on FlyerTalk.
As with previous missing plane threads, please observe the following in this thread:
1. The normal FT Rules apply. (Including not discussing moderation actions on-thread). And please be particularly attentive to "discussing the idea and not the poster" when you have a disagreement. Civility and mutual respect are still expected and are what we owe each other as a community.
2. You are expected to respect our diversity, and therefore refrain from posting inflammatory comments about race, religion, culture, politics, ethnicity, orientation, etc." Do not cite, copy, or report on such.
3. Please do continue to be attentive to the sensibilities of the families of those on the flight. Think about if you were them what you would and would not want to see posted. Reasonable speculation about what happened is permissible; please, though, do not indulge in inflammatory or overly-lurid descriptions or depictions (or links to same) that could well be hurtful.
4. Overly / extravagantly exaggerative posts such as conspiracy theories, posts beyond the realm of science and known facts, etc. as well as posts with information that has been posted several times previously may be summarily deleted. Moderator actions may not be discussed in posts on FlyerTalk.
(For those more interested in conspiracy theories and have access to OMNI, please post here: OMNI: Search launched for missing AirAsia jet bound for Singapore from Indonesia)
5. FlyerTalk complies with international copyright agreements. Please do not post full copyrighted articles; summarize the salient points, cite properly and post links. Entire copyrighted articles will be summarily deleted.

Search and rescue operations are being conducted under the guidance of The Indonesia of Civil Aviation Authority (CAA). AirAsia Indonesia is cooperating fully and assisting the investigation in every possible way.
The aircraft was on the submitted flight plan route and was requesting deviation due to en route weather before communication with the aircraft was lost while it was still under the control of the Indonesian Air Traffic Control (ATC).
The aircraft had undergone its last scheduled maintenance on 16 November 2014.
AirAsia has established an Emergency Call Centre that is available for family or friends of those who may have been on board the aircraft. The number is: +622129850801.

Correcting other media reports the chairman stressed that none of the bodies recovered so far was wearing a life vest. All valid information concerning QZ-8501 only and only comes from one source, namely the Search and Rescue Service which is currently in charge of the entire operation, the chairman stated with reference to the current information chaos.

As there are some truly distressing images emerging from the scene please be reminded to refrain from posting these or linking to them in line with the moderator guidelines.

According to Indonesian officials, debris in sea '95% likely' from AirAsia Flight QZ8501:

That is just outright slanderous language. AC 190 isn't even a thing" as the rudder has not been damaged despite the horrible wrongdoing of the pilot.
To blame the most reliable shorthaul workhorse on the plane to be 'susceptible' to a failure mechanism is suggestive language that it actually has happened. A few times.
Also, the NTSB article addresses purely wake turbulence, not weather. And it requires pilot errors .. A320 design flaws are at the very bottom of the list of probable causes.

There is no particular indication that A320s have a susceptibility to icing. Indeed the only A320 hull loss in which it was even a factor was G1 888, and in that case it was an AOA sensor that was frozen, but due to water sprayed in from a hose on the ground.
Even if the pilots of QZ8501 had encountered severe turbulence, there's always the 180 -- just turn around and head back from whence you came. Furthermore, if they had encountered persistent severe turbulence and not just some bumps, we would probably expect to see a slower airspeed. Although I don't have an A320 FCOM, from some notes I found online, it appears that Va would be about ~283 knots [edit: calibrated airspeed] for their altitude, while the last flightradar24 return has them at 469 knots [edit: true airspeed, equal to about 295 knots calibrated airspeed]. It seems likely that with turbulence severe enough to cause an inflight breakup, they would have pulled the speed way back.
As I said up-thread, there's no compelling anecdotal evidence to really speculate on at this point. Given that there was adverse weather, of course it will have been a factor in the planning an execution of the flight, but there's no indication that it caused an accident.

This is standard operating procedure for all major airlines. A crisis plan which includes counselling and support services, away from the public eye, is as far as I know in place. I also understand that AirAsia cooperates with the respective airports in providing professional support.

Furthermore, if they had encountered persistent severe turbulence and not just some bumps, we would probably expect to see a slower airspeed. Although I don't have an A320 FCOM, from some notes I found online, it appears that Va would be about 300 knots for their altitude, while the last flightradar24 return has them at 469 knots. It seems likely that with turbulence severe enough to cause an inflight breakup, they would have pulled the speed way back.
Also, it appears that debries are not spread over a large area. This would suggest that the aircraft did not break up inflight, but more likely to have been intact at the point of impact.

AirAsia Indonesia QZ8501 SUB to SIN reported missing 0724 Sun 28 Dec 2014
From aviation herald:
On Dec 30th 2014 Indonesia's Search and Rescue Services reported, that they have located the wreckage of the fuselage at the floor of the Java Sea, about 97-100nm southwest of Pangkalan Bun. The aircraft is broken up into several large parts but well recognizeable.
