CAA personnel read Rotorheads - some even contribute to discussions - so the chances of this thread coming to the attention of the CAA are very high.
In addition, I am reliably informed off-forum that at least two formal reports have been made to the CAA this week.
All credit to LQ71 for raising his concerns here and thanks to those who've offered helpful advice. It will be interesting to see what happens.
