Actually BPA I think that SIA leased the building from Aeromil in the first place. Might be wrong on that but I thought thats what I saw when I was up that way in 2008.
Dora-9, I think you might be correct is suggesting that the operation will not be moved elsewhere. SIA has the capacity, like QANTAS to educate their new starts as SO on long haul. IIRC, QANTAS got rid of the HS-125s' when simulators became available so there was no need to run people round in mini-jets any more.
