Issue will be that it will be 5-7 years before you joining post University.
Bearing in mind that number of opportunities has decreased massively over last 20 years and will continue to do so. Therefore better asking yourself this honest question.
What skills can I bring to RAF FJs, that someone who doesn't need corrective surgery could bring, without it challenging RAF medical regulations and peoples time ?
If you read the topics on here you will find people telling you of the drop out rate and skills required but question then is what is your fall back position ?
Assumme that you were succesful in getting accepted onto the initial courses.Then 2 years later you drop out because in all honesty instructors deem you not fit to fly FJs, what then ?
For some they will go onto other things in RAF and have succesful careers, for others they spend next 10 years in depression with a belief that they were wronged.
So now you think that in 9-10 years time that everything has worked in your favour and you 25 but deemed not fit to fly FJs..................what is your alternate plan ? or will you have spent 10 years working on something that was always unattainable ?
Being deliberately negative here because your ambition is worthy but if spend years trying for it and it was always unattainable then what have you walked past in life ?
