There was also a problem with the prop hubs on the Vigis that needed inspecting.
I heard that OC 2FTS was flying when the recommendation to pause flying in order to take stock of the situation (read, old fashioned grounding). I'm sure that OC 2 FTS woukd have preferred not to have interrupted his flying!
I suspect there are other, more commercially sensitive reasons, why we haven't heard the full story of this 'pause'.
