I went through OASC this year, applied for Pilot and WSOp, passed everything for both, then got told my legs were 14mm too long for pilot; bugger. Oh well, take it on the chin, its not meant to be - I was absolutely chuffed as chips to get WSOp, and given the option between a great career in the back of a a/c doing a job I'll love, or coming down on a chute with no legs because your knees lost a fight with the instrument panel, I know which I'd choose.
Don't be bitter about it mate, the rules are there for your safety and everyone elses. My reviewing board officer said that they aren't out to shatter hopes and dreams, they are there to filter out those with the right stuff and those without, and they would be irresponsible to pass people through who might later put themselves, their colleagues or those on the ground in danger - wise words.
