It's not as bad as all that. The best time to start planning for the current wave was about ten years ago, so as to be in a position to get hired shortly after 2012.
But the good news is that the retirements don't just end in five years, or in 2030... it settles down to a slower pace but still respectable by historical standards (as always subject to growth or downturn.
Also industry growth projections are consistently quite rosy, both global and North America. I'm actually consistently surprised every time I see those, but they must know something I don't. I think it's based on known population growth and assumed economic circumstances. If even some of that pans out, the hiring will continue for many years, although not likely at the levels we see today. Yeah, they probably need green fuels and airplanes for long-term growth.
