When it comes to an incident/accident, I don't think "silence" is an appropriate response.
Some people know to do the right thing, others only do when pushed and others don't know what is right.
Unfortunately aviation is in the public area for all to see the results of a bad decision. We must all accept that our actions in these aircraft can and will be called into question from time to time and reasonably so.
Hence if u don't know to do the right thing, would the knowledge that big brother is watching make you do the right thing?
I hope it would not need to.
Anyway as I said too many mates lost due to stupid stuff becoming a part of the operational culture..... Safety, safety, safety..........
