DP - in the bad old days it was the Bulldog that was the limiting aircraft. Anyone who was borderline at the medical at Haslar would be fitted with a helmet, taken to Southampton UAS at Hamble and plonked in a 'Dog for a full and free check.
I only knew one such person. Cocky bugger, and he did no work in the second term at BRNC. Must have failed the attitude test too, as he was chopped with no chance of a re-scrub.
