Everyone: I closed this thread for a short while to remove references to a pilot who appears not to have been on board and to have been incorrectly named elsewhere (perhaps also by some French authority sources).
Naturally this will be distressing for many people, so I would ask that we wait a while for a further official announcement naming those on board.
As an aside, some people posted comments in this thread along the lines:
Please delete the incorrect posts.
That's fine, but by far a quicker means of getting the Mods' attention - as one person did, so thank you - is to use the "Report Post" facility that you can find under the cog icon at the top right of each post. Thanks very much.
I have also split off one post quoting well-placed sources suggesting the accident cause was known. This places the Mods in a tricky position - we do not know what credence may be placed on such sources, or how informed they actually are. The possibility of an incorrect statement being made is sufficient for us to ask you please to not do that. Once again, thanks very much.
