Firstly, I do not fly from Sibson, and have no involvement with them other than having flown a couple of times with Frank a few years ago. So I'm afraid any accusation of being an "insider" will be a misplaced accusation. In my personal experience, Frank was a very good instructor, and I have heard the same opinion from more experienced aviators than me. Whether his paperwork is up to scratch, I don't know, but I also know several other instructors / examiners who are not always the most organised in paperwork terms. I also know bose-x, and if he says he can help, he probably will, but my sense is that he won't have intended the cluster comment to be seen as so derogatory. I am sure he can speak for himself.
Secondly, I am amazed at the aggressive nature of the demands that are being made by people who are not even the aggrieved party. It makes me sad to think that people can be so quick to judge on one person's story.
I do hope the paperwork can be sorted soon, whatever happens.
