I had a friend who kept telling me about his time in the army but never got into much details. Not because he was involved in anything top secret. It was because as he admitted to me some years later. His time in the army lasted a matter of hours. I was not surprised, just like Frank Spencer he was someone not cut out for the armed forces.
Frank gets ready for his annual RAF reunion party. Only no one present can remember serving with him. Frank cannot remember which RAF squadron he belonged to.
Flashbacks show just how inept Frank was at basic training. His instructors wanted to get shot of him fast.
It starts with a brief guest appearance by Desmond Llewelyn as Air Commodore Drew. It ends with Fulton Mackay playing an aptitude test supervisor. He is exasperated by Frank.
Once again there is physical comedy but the funniest scenes are with Mackay. I just did not know how the latter managed to do it without corpsing.
