Only just started reading the SI report but already I feel compelled to note that para 1.3.3 footnote 5 uses vatsim.com (an online multiplayer ATC simulation game) as its reference for the description of the "Lichfield Radar Visual Corridor". Maybe if the panel had used (say) the UK Mil AIP as their reference, they would have found that it is a "Radar Corridor". Tantamount to citing Wikipedia, I find this astonishingly unprofessional in a document of public record.
I sincerely hope that this trivial example isn't indicative of the quality of investigation and research to come. But it does make one wonder.
