An sad example of why it is a good idea to get the word out before even the "official" report is issued comes to mind. I'm not going to mention detail but it was a long time ago. "Control reversals" during maintenance are all too common. One occurred and the pilot was killed. Rumor was it was negligent maintenance, an aileron reversal. A bunch of us used to get together early in the morn for coffee. This accident came up, one pilot blew his top, as he knew the mechanic and didn't want someone knocking his friend with speculation. Later, it was confirmed that the mechanic had screwed up. Unfortunately, between the time it was made official and public another identical accident occurred for the same reason and that pilot also died. I have to believe that if the possibility of the control reversal on the first had been widely publicized the second tragedy might not have occurred.
