Your post strikes both a pompous and naïve chord.
The investigation is not duty bound to immediately publish every single finding nor explain their actions or methodology so that the media and internet pundits can dissect every detail in their usual ignorant and often downright stupid way.
When they have something constructive and helpful to say they will say it. So far they have nothing to add to what is known that would be of the remotest use.
It is quite pointless to waste time distracting busy people with pointless demands when there is nothing to be gained.
And, by the way, it is British Airways not British Air as so many Americans insist on calling us.
