as the gliders were no different at the end of the week to what they were at the start of the week.
If there was a worry about a potential airworthiness fault at the end of the week, then what had already NOT happened at the start of the week is immaterial, I'd have thought.
MUCH more important is the loss to the credibility of the organisation if something had happened which would most certainly have been prevented by a grounding.
You can't have it both ways.
