Quite a few people left Virgin around 9/11. Some were commuters who got sick of commuting and some were people who got demoted because of the 9/11 effects and were too proud to go back into the right hand seat! If they'd stayed they would all be back in the left hand seat earning a good salary with good conditions.
The people who left because of the commuting seem to enjoy the orange tails, the proud ones however are probably kicking themselves!
