What 'event' needs a 'statement' pray? In airline annals, it is one of the lesser important 'events'. A flight diverted, a crew member left the flight, flight continued, everybody landed safely after a minor 1 hour delay. What more do you need?
Well on that basis you're right, a complete non-event! Except that of course it wasn't quite that simple. This was a flight that seemed to have some (outside of your sphere) very unusual behavioural difficulties that caused an international flight to divert for no other known technical reason. Flights divert every day without anybody batting an eyelid. This one attracted the attention of the media and certainly the aviation media, by virtue of some seemingly unusual circumstances. On the basis that of the 582 contributions to this thread so far, no less than 7% (42) of them have come from you! Having so much obvious comment or interest yourself, it is a little autocratic to suggest that anybody else with a degree of interest, should keep on walking!
Much of the interest is borne out of, just how unusual a situation this appears to be. However your experience and comment would suggest it is not as unusual as some might think? From a professional standpoint that might clearly raise some alarming markers. Whether United make any further comment on this issue is clearly a matter for them and the individuals concerned, but the underlying issues and their greater or lesser concerns to the wider industry are clearly cause for comment and debate here, as you yourself so obviously demonstrate.
