Actually I think the memorandum says 4/7ths from
VB!
From the document:
At least 4/7ths of the complement of Captains will be recruited exclusively from Captains wthin Virgin Blue
The next line basically says that the remaining 3/7ths can be made up from Captains from both internal and external channels! (but I can't be bothered typing it in full!
)
