Shaun,
I am not saying they should still be exactly like that by the time they get front line, that is for flying training to sort out, but there is nothing wrong with the attitude before joining.
You may not like it, but Gung Ho people form the basis of any decent military force, particularly your own Royals!
See what happened recently in Iran. A shortage of gung ho in all quarters.
Contrast with strapping booties to the outside of Apache. If it had failed it would have been held up as an example of all that is wrong with gung ho boldness.
BUT IT DID NOT. And that is what makes the british military great.
