manipulation???
Koudelka,
Your argument is weak. It is only your opinion but lacks sustantive data.
If "millions" heard a plane falling ,why donīt you find a couple of them, ask them what they heard and then tell us if they have some valuable information.
A witness that saw the plane falling may be of some value. The investigation will determine how much. However, the FACTUAL information released by the aeronautical authorities is quite valuable (radar traces and communication excerpts).
The opinon of the City Major and other authorities that do not have experience in aerial accidents is just that, their opinion. It is hardly manipulation of information.
To prevent this event from becoming a conspiracy it is necessary to have cool heads that can think. Hopefully you are one of them.
