Like Brakedwell I also did the 12 week course at Kirton Lindsey in 1956. After 2 weeks leave found myself on Empresss of Britain en route to Canada. In those days "officers" always went first class. So, dinner was in mess kit (Best blue, white shirt and bow tie). One important thing IOT had neglected was to teach us how to tie a bow tie. The cabin steward had to complete my officer training.
