An airline industry forecast is raising concerns about a pilot shortage.

FOX News Radio's Lilian Woo explains:

Boeing predicts nearly half a million new pilots will be needed worldwide between now and 2031, as global economies expand and airlines take deliveries of tens of thousands of new commercial airliners. One of the world's largest makers of those jetliners also predicting more than 600 thousand new aircraft maintenance technicians will be needed over that same period.

A possible shortage here at home officials say could be touched off by rising global demand, combined with an anticipated wave in retirement and tighter qualification standards for new pilots that will kick in next year.
