Pros
Nice atmosphere with great colleagues. Easily the best place I've worked at for making lots of contacts. The work is very unique: outfitting VIP aircraft is not something you get to do everywhere. Work safety is taken very, very seriously, never seen anything like it.
Cons
No career opportunities if you don't belong to the clan. This goes for most departments. Nepotism runs wild: Many people hired because they know someone, not because of skills. Wages are way below standard for the area. Overtime will be your new standard, many times not because the workload wouldn't be doable within normal working hours, but because of blatantly obvious inefficiencies in the processes. Shift work is regularly implemented out of the blue. Much of the engineering work is being outsourced to the other side of the world: Quality is often lacking. Emphasis is put much too strong on keeping shareholders happy: It is also the very first sentence on the welcome booklet you get. Overall a rather disappointing experience. Not a place to stay for too long.
