Thanks, G. As with most societies, you'll only get something out it you put something in. I also feel that it looks good on a CV, in that it gives the reader the impression that you're serious about aerospace and aviation.
The useful nature of the library in boning up on companies is, I'm sure, directly proportional to your proximity to London. Its a bit of a trek for those of us on the auld sod.
Still, I've got an interview with a large (and very famous) aerospace company next month for a graduate position, and I'm sure the GradRAeS on the CV didn't do me any harm. Touch Wood.
So I think its worth the subs, Jinkster, especially if you intend a professional aerospace career.

PS sorry about the erroneous H Genghis.
