Apologies for continuing the thread drift (I am one of those who cannot understand the mentality of anyone who thinks it acceptable to take phones, videos or music into a live helicopter cockpit...); I think the SH songbook occurrence refers to the one which future Air Marshal TJ endured at Odiham. On extracting himself from the wreckage, he walked in the line office and entered a fault in the F700 along the lines of "when AFCS engaged on ground, aircraft rolls over onto its' back".
