There is a lot of speculation that Daesh brought down Metrojet Flight 9268, a Russian civilian airliner, over Egypt. This is both behind the scenes and in the media, and it brings up some interesting points for consideration.
First, it brings up the point of what did happen and how that is handled. In the US, airline, railroad, and other similar accidents fall under the National Transportation Safety Board. Yes, they can and have investigated more than airline incidents. One of the best legacy products of the now defunct Aviation/Space Writers association is a booklet called Air Accidents and the News Media. If you can find a copy, it gives a good breakdown of what happens, when, why, and who is authorized to talk at any given point. The actual process used is designed to allow a complete and impartial investigation and to avoid political interference in same.
Sadly, the latter is needed as politics do come into play. It has since the early days of the railroads and continues today, and my thoughts on current and recent administrations eagerly coming out with immediate denials of terrorism should be easy to guess. The early, and often completely unfounded, speculation about any accident/incident is not helpful, and flat out wrong. It does, however, give the media and politicians ratings and a chance to grandstand.
Getting real data is time consuming, and involves a lot of engineering and non-engineering forensics. It means testing each piece of debris, and often requires that the pieces be, in effect, re-assembled so that a full and accurate reconstruction of events can be developed. These days, it also involves a lot of computer modeling, which is a time-consuming process in and of itself -- and GIGO is very much on the minds of those involved. Those involved via the NTSB and similar agencies around the world tend not to talk or leak, knowing that while pieces may be sensational, how they fit together can provide a very different story.
In my personal opinion and experience, the first speculations are often wildly wrong. The mid-phase speculation is more on target. The final report is (at least here with the NTSB) is accurate, fairly complete, and somewhat boring to read even when the results are significant or even spectacular. I will also note, for the conspiracy theorists out there, that I have never seen a final report that was clearly changed or whitewashed -- and trust me, given the hundreds of people that end up involved it would be very hard to keep such an event secret. I will also note that not every country follows our model.
We are into that middle period of public speculation, and it is interesting to say the least. While there were early reports of the co-pilot being unhappy with the condition of the aircraft, there is a lot of back channel discussion of involvement by Daesh. This is now coming out in public announcements, and I do find it telling that the UK has stopped direct flights to the UK from the Sinai. This is not, however, definitive by any means.
Which leads to a second major bit of food for thought. The Russians (and the Soviet Union before them) tend towards direct action when terrorism is involved. For our older readers, I simply will say Beirut, though there are many other examples.
If this was indeed an act of terrorism, I suspect that the apocalpytic cult that is Daesh may well get some of what they seek. Speaking strictly for myself, I will simply say Владимир: Добрый Охота! Your mileage may vary, and if so sound off in the comments.
