King Hussein of Jordan - thoroughly nice bloke - I met him.
All Jerry Rawlings' bios state that he won the Flying and Airmanship award in training, and then there's no mention for 9 years of aircraft or squadrons till the Coup.
Possibilities:
1)He's the World's only modest fighter pilot........
2)No aeroplanes serviceable, so did ground jobs
3)He got medically dropped
4)He failed a later stage of training
