Brad, in the Uk and Oz at least maintenance technicians such as myself are quite rightly known as Engineers.
There won't be many design Engineers allowed to fly in the jumpseat on commercial flights anymore as the rules on this have tightened up considerably.
I flown the jumpseat a handful of times and although its interesting and the crews have always been very friendly it's far more desirable to fly in the cabin in comfort especially after a long job away from home
