...not to mention the effect of the aging airline fleet. Older aircraft, many from the '60s are nearing, and in many cases, have exceeded their cycle design limits. They've been overhauled numerous times, hush-kitted and resold on average (I would guess) about twice by now, winding up for the most part in the Third World. With the double-edged sword of a fragile mechanical state combined with a maintenance program that (how can I put this delicately) is probably slightly less excellent than those of the majors, I unfortunately expect a substantial increase in the overall hull-loss rate in the next decade.
