The nice TRE a few weeks ago failed both FMGCs on an A320. Then our slats jammed during the procedural approach ILS into Malpensa. The extra fun bit? The loss of both FMGCs mean you don't get VFEnext displayed, so you better start writing down VFEnext-5 for all your flap stages. While trying to remember how you manually tune the radios

Of course no A/P A/T.
Oh, and procedural ILS was due to the radar having been knocked out by the storm over the airport (and all the alternates). Needless to say, a missed approach would have been interesting (for those of you who know MXP...).
Skipper and I fell asleep about 5 minutes after getting into the taxi from the sim building
I know thread drift, but worth sharing a beautiful sim moment.
