I have another view about the report.
While I accept all the comments about the English I was extremely impressed with an organistion that went into so much technical detail during the investigation. Given that there was a great deal of RAF 'history' about fires in Lightning backends (as well as canopy issues preventing ejection), the investigators could almost have been excused if they had done a few paragraphs referring to the similarity with the past and left it at that.
Apart from the English I don't think the content can really be criticised. Mind you perhaps one does need to study the very lengthy and detailed report to hold that view.
