I wonder if the forecast is ever trimmed down to factor in reduced maintenance schedule of plastic aircraft and the inevitable, eventual introduction of reduced pilot/pilot-less aircraft.
Just by doing a quick search of jobs out there for engineers on Boeing and Airbus type aircraft, there seems to be the opposite of a shortage going on.
This will surely be compounded by the mass introduction of B787's and A350's and the MRO's currently geared up to do heavy maintenance on the previous generation of aircraft, 330's, 747s, 737s, a320s etc having empty hangars for stretches at a time.
