The judge's sentencing remarks have now been published:

He is sentenced for offences around endangering the aircraft but not for the consequences. He is described as a an experienced Commercial Pilot but so far as I can see no mention is made of the RAF - presumably that point came out in wider evidence during the trial.
Read in its own terms the note is a pretty damning indictment of Henderson and his attitude to operating charters of this type. Ibbotson's failings had been flagged for him by another passenger and by the fact that there had been MOR's regarding (1) an infringement of controlled airspace and (b) runway infringements while taxying.
