Unfortunate turn of events, and flight deck crews understandably reluctant to go until the matter resolved. Apparently some arm-twisting going on behind the scenes led to some crews departing before any written confirmation through that the matter was in hand.
Can't have been fun for the STN pax on stand for almost 2 hours sat in the a/c, but I suspect I know who would get the kick in the n#ts if the CAA had ramp checked the a/c (and it wouldn't be an administrator). Sensible choice guys - hope the management see it that way too.
