Boslandew, don't be too bothered. In most probability the crash site was covered in cloud/fog. However, the whole argument remains centred on the 'absolutely no doubt whatsoever' criteria required for the Gross Negligence verdict. Most accept that the crew probably got things wrong but, without irrefutable evidence and in accordance with their own rules there is no way that the MOD should have reached their verdict.
Throughout, the arguments that have been put forward on this forum and in other places are those that highlight the various doubts that completely undermine the verdict. Of course, other things such as airworthiness then come to light and these demonstrate the hypocrisy whereby a crew are blamed without the ability to defend themselves whilst the accusers, who willingly contravened the MOD's own regulations for airworthiness, continue to sip sherry in their gentlemens' club.
Ask yourself how many other aircraft have rammed hillsides during the last 100 years or so, with greater or lesser evidence, and how many of these crews have been found grossly negligent.
That is where the gross injustice has taken place.
