So, a probable cause is established with OT and
JS providing plausible, possible reasons. Good work, what's next? Will it now get complicated, does 'steel' and manufacturing need to be analysed, followed by a paperwork check to see if any 'suspect' parts are fitted and replaced if they are identified. Or will it involve the whole fleet in a health check?
Liked the bit in
JS post where young Bloggs just bails out, bugger this for a game of soldiers says he; wonder how many beers that cost him. Good bit of kit the parachute, even if uncomfortable sit on.
