Dont forget though that SIA has had a lot of ex-BOAC/ BA pilots - and always had - plus QANTAS and other major world airlines pilots with them, having left their companies because they had taken early retirement. When I was there we had hardly any locals flying as Captains. I dont know what its like now of course.
Not to take away from BOAC/BA expertise . I have often come across this attitude of the poster who said that BOAC crews and its successor were arrogant etc. It largely stems from jealousy that we had a marvellous airline. (And they secretly wanted to be in it!!!!!!)
