I work for an aerospace cabin integrator and we're always looking for good TechPubs people. My company offers fully paid classes within our field. The great thing is that the TechPubs folks work hand in hand with the engineers. You can talk with them and figure what type of engineering work you want to do, stress, electrical, structures, flam, systems, furniture... and we just touch the inside of an airliner.
