It might be worth considering that the F/O didn't notice the 270KT with flap 5 exceedance.Rushed stressful approaches can max-out the most accomplished experienced operator and this guy,don't forget, was way outside his comfort zone and may well not have noticed an exceedance of only a few seconds in duration. I know most info is IRS derived but,if the sideslip was of any magnitude would the IAS be 100% accurate,maybe no exceedance was visible? Not trying to defend anybody but the poor guy was less likely to rock the boat and strand everyone in Skavsta for "only" a Cowboy approach followed by a flap 10 landing.When the monitoring system first came in pretty much everyone knew that a breaker behind the F/O marked WQAR meant watch your ass if you had a "hot" approach;they all have it now, but it amazes me they could have niavely believed they would get away with it if they knew the system was in-situ.Incidentally it is possible to land safely from where they started down without any abnormal control inputs/exceedances and respecting the RYR" approach-gate"( ie configured/spooled up/stable 500' VMC)it merely requires the application of the correct technique,( dirty&down not down &dirty or worse still half&half,which is what they tried).Seen it in the sim,wouldn't recommend it as a normal technique, but yes,they could have got in with no histrionics if they had applied a better method of flying the damn thing.I never met the Captain so have no idea if the boozing&fornicating(oh yes please!) accusations have any foundation, but those who pooh-pooh the broken marriage scenario obviously aint been there. . .yet.Command of an aircraft is not the place to be with a troubled mind ,but how many of us really call in sick if we are distracted/pissed off/ angry? and no I'm not just talking about RYR.Hell there are guys I have flown with who seemed to be having a crisis every day. . .what do you do? phone the CAA/IAA and ask to have them grounded/commited? I suspect most of us try and get through the day as pleasantly/normally as possible and leave it at that,unless it is someone we regularly fly with and it starts to grate.
