Do military aircraft such as the Hawk in question have flight data recorders or CVR's fitted to them?
Not in my time they didn't (thank god!). Not sure about now but I, personally, wouldn't think so. ^^^^^^ I accede to greater wisdom above! ^^^^^^
IIRC Thursday war 'let's be a missile' jaunts were normally done solo. Often taking a punter in the back for a jolly. If that's the case today then I guess the ballast got more of a ride than they though they might and the delights of the MB tie and subsequent after dinner dit!
Best wishes for a speedy recovery to both!
