Now as much as you may find the originator of this post and their comments immature, perhaps it would be better to criticise constructively? Then instead of being disheartened and thinking that everyone in the RAF are full of themselves it would help motivate them to get their act together.
I have come across many pilots in my short life and most have been friendly and helpful and willing to help a young wannabe where they can. A few have been extremely unhelpful and arrogant, believeing that if you don't personally know it you should shrivel up and die or so it would seem. Most, but not all, of the latter category can be found on here. Similarly there are some helpful posters around too.
If you insist on posting here, realise that young people - probably very much less mature than yourselves - who are looking into a military career in aviation will ask questions. If you don't like it then put yourselves in their shoes before criticising, you may just be surprised at what you see.
