A refreshing change to see some 'Developing Country' government holding 'Airline Executives' responsible for failed financial management or extreme private decisionmaking without due consultation. A lot think they are 'God' and above that sort of accountability, or can make it go away with a little 'Grease'.
Mind you the Vietnamese Authorities can be extremely hard to get on with, certainly were when we were there.
Our Company had a good relationship with them in general, but they were absolutely furious with them one time, they insisted on seeing the Certificate of Registration (Australian) for our aircraft. Our Company offered to send any number of copies of it but that was no good. Then they offered to send them certified copies of it certified by CASA, and when that was rejected certified copies of it certified by a Judge, still no good. Reluctantly they ended up having to send the original up to Hanoi hand held all the way by a Courier. They had never had to do that before or since with any other Country.
