Le 20h de France 2 : journal télévisé du 25 juillet 2014 en replay
Go to + 11'10'' to have the beginning of the topic. Comments are in French of course but the most interesting is the video.
This capture could not have been filmed in France were all matters about aviation and ATC is stricly monitored and considered as a secret of State.
I think that the officials aviation authorities in Burkina Faso allowed journalists to do their jobs and shown all evidences in their possesion. This is totally unthinkable in France (and likely in other countries...)but it was done
before the Malian government requested the assistance of France in the inquiry. Now all the military behaviours are in place and nothing will filter. Fortunately the Burkinabese were not told to refrain from unveiling this record.
