Post in wannabes if you want the lowdown, and take a look at the past queries along a similar vein in 'search'.
It all depends what you are capable of as a person - if you can get a good degree from a good university, then go for it (subject to cost etc).
If you go to a poor university, you are only wasting your time.
Take a look at
www.dur.ac.uk/nuas for all about UASs - a good thing to have a look at while at uni, and especially if you want to fly in the RAF, and hence get free training.
Major plus is that a backup career can be pursued if you lose your licence medically, there are few jobs in flying (as at the moment for newly qualified pilots), or you can fund your own training better, especially if you end up earning loads post-uni (and if there are jobs in city areas etc!)
