Virgin have not recruited any fast jet pilots (no base training) for a number of years as the priority has been rated pilots and ex mil with heavy time, therefore only ZFT conversions carried out.
With the cadets coming on line in the future, base training will commence again opening up the opportunity for ex fast jet guys and girls. I can tell you from experience, no recommendations from current VAA pilot carry any weight in the recruiting process, not even getting an interview. Like most, we are a HR department with an airline tagged on the side!
