As global economies expand and airlines take delivery of tens of thousands of new commercial jetliners over the next 20 years, there will be unprecedented demand for people to pilot and maintain these airplanes. To meet this tremendous growth, the 2015 Boeing Pilot and Technical Outlook forecasts that between now and 2034, the aviation industry will need to supply more than one million new aviation personnel—558,000 commercial airline pilots and 609,000 maintenance technicians.
