Pros
Lots of friendly people & sometimes very interesting work. Employer is usually there when you need them for any help. The Company has a good reputation because they are in Space & Aeronautics.
Cons
Too much politics about every decision. People at the "coal face" never consulted about anything. Jobs will be placed in your lap with no prior consultation & ridiculous deadlines that you will have no hope of meeting. Don't stay too long or your skills will not be very saleable to new employers. Bank on 5 years maximum then secretly apply for another job. You can easily get into a rut & never be promoted. Don't ever criticize or complain about anything or you will become the problem. Stay as quiet as a mouse always speaking in hushed tones even if a problem is so big that the company could lose out badly. Never make out that extra unpaid hours are causing you stress - always smile no matter how bad you feel. Never go to HR if you have a problem - don't trust them.
