Interesting about the timing of the diversion and captain's knowledge. If this muppet was somewhat fuzzy when boarding it is >1.00hr from STN - SXF. i.e. well into the flight. I was just curious how long it was before the volcano reached critical pressure. Equally, as has been mentioned, SXF seems well off route to Bratislava. Looking at a google map I would have expected them to be closer to HHN than SXF, assuming a diversion into a RYR base would offer better & knowledgeable ground service: also a base captain to represent RYR's interests in any immediate action & follow-up.
