India Four Two,
Having read Legalapproach's post I wonder if your "complete" disagreement with my view might be a little less complete.
It seems to me that the CPS and even the CAA have a poor track record for prosecuting pilots. A lot of this has been thanks to the efforts of Flying Lawyer before he became a judge. As far as I recall, most of the cases I know about have revealed a readiness by the CPS or CAA to prosecute on unreliable evidence, causing immense distress to the unfortunate pilots. In at least two of these cases, the unreliable evidence came from professional pilots, as in this case.
Until I learned more of the real situation, now revealed by Legalapproach, I too assumed that this pilot had been stupid and should have been prosecuted. Although he may have demonstrated poor airmanship, I do not now believe that he should have been prosecuted.
