Iceman, how is defining "engineer" disrespectful?
Down south in ColonelAngus land, a guy or a gal who works on airplanes is an A&P mechanic and his certificate states "Mechanic: Airframe Powerplant."
Engineers are electrical, mechanical, chemical, civil, environmental, aerospace, etc.
Those who are not in the know can be confused when an airframe mechanic in Hong Kong calls himself an engineer.
