Political View
There is a slightly uncomfortable message in this incident regarding the way in which Politicians operate.
From the data they subsequently presented, the American Goverment (and probably the British and Canadian Governments) knew that the Flight had been attacked by a missile(s) within an hour. Despite this their public attitude was “Terrible event, but let’s see what comes of the investigation”. Only when 3rd party information started becoming public on the Web did they release the information they already had.
Presumably this lack of positive action was designed to ‘calm the waters’ after Iran’s earlier Strike. It does show however the extent to which Politicians tell you only what they want you to hear, even under these types of circumstance.
