Whatever the circumstances the 2 following things are true
1. VTS did not appear to submit a PtF application in time.
2. VTS, knowing that there PTF, had not been applied for in time, continued business as usual, even though it was obvious that the Vulcan would be grounded pending resolution of the issue.
No matter how people defend the circumstances how how things got this way, its clear the VTS's management really messed the whole thing up and its now time for a change, otherwise there will be zero confidence in their operation.
