B&B,
I believe that there were around 140 in the pool at the time. BA has a policy of keeping people in the pool for only 1 year after which time you fall out and have to reapply. In 2008 they stopped courses and so people were sat in the pool with no chance of being fished out. They extended the time in the pool to 18 months but then decided to disband it.
Only those with the right TR would have been able to reapply, there were many mil guys in the pool who couldn't.
regards
