Strewth - you really asked for that lot! Consider - don't you think your initial post came across as a tad narrow-minded and therefore unlikely to get "serious" responses to the questions you posed?
Problem we have got with you sport is:
a. R U just a wind-up merchant?
b. R U serious?
c. From where / what are you coming from?
Solution is:
a. When did you join the RAF (full time)?
b. As what?
c. What do you fly?
d. As what?
e. What did you want to be doing?
Read and digest some of the answers you got. The "English" corrections you REALLY asked for. Some of the other "pearls" should give you sage words to ponder as you continue to learn every day of your career
