I understand that doctors have at least six months' work in hospital after they are qualified and before they are called up for the R.A.F. Many of them are then posted to stations, some of which, no doubt, are isolated; but I would remind my hon. Friend that it is on the stations that most of the medical work of the R.A.F. is done. All general hospitals in the R.A.F., however, organise regular clinical meetings, to which medical officers of surrounding stations are invited. In this way, most of our doctors can improve their knowledge, if they feel that their ordinary work does not give them experience enough.
