ditto biscuit chucker et al, go for it.
It wil give you a greater understanding of what cabin crew do which benefits you and your cabin crew when you become a techie.
word of warning - neither cabin crew nor pilots will want to hear about your flying prowess ad nauseum. cabin crew will feel you are trying to show you are better than them and pilots will feel you are trying to undermine them. Both groups will feel you're a ******.
Have fun!
