KYT's comments are correct -many senior guys on the 400 were held back from moving onto the 78 or the Bus too maintain a certain level of experience on the fleet- however they were assured that their positions would be safe in the event of another crisis and now they have been double crossed.- I sincerely hope that they have saved documentary evidence of this at the time it was published.
Some of the more senior guys have given the company 25 years + through thick and thin & yet guys who have been in the company less than 4 years will escape the Axe. What ever happens at Virgin Atlantic Airways things will never be the same.
