We lost several during the early 80's due to our unfamiliarity with their manoueverability and g loading.
Manoeuvrability and g loading are very similar to the Hornet's. The F-15/16/18 series was a novelty, in terms of manoeuvrability because they were the result of John Boyd's studies about just that. No plane before then were built the way these were/are built using the principles preached by Boyd. Yes, there will be other challenges (the Helmet being one), but with today's simulators, I don't think we're going to lose as many JSF as Hornets.
If you take said bird up the intake of a single engine aircraft you get an ejection, just like the guys in the Hawk in Moose Jaw. If you're in the Arctic far from civilization, you're probably going to die before anybody gets to you; that's just the way it is! McKay can guarantee all he wants that there won't be engine failures; but I did my time wearing blue, they're going to happen, for any number of potential reasons!
Are you really comparing that shitty Adour engine to the P&W F135? You can't even compare it to the Hornet's engines. They were designed and built 30 years apart.
I agree, they will fail. It's designed by a human, built by a human, maintained by a human and operated by a human. It will eventually fail. However, I believe their fail rate will be much lower than what we are used to. In the end, it's risk management. How many catastrophic engine failures did we get in the last 30+ years? Pretty much everybody I know had to shut down and engine at one point or another, however had it been the only engine, you can bet we would have milked that engine all the way to a place to land or punch out safely.
As far as not having contingency planning for attrition, well, the line will be opened for many years after we buy them. I am sure that when the needs come to get new airframe, we will be able to buy more.
In the end, the JSF is great for us. It brings expertise and technology in Canada, by having companies building parts and we get a cut on every JSF that is sold, being a participant nation. If we were to pull out of the program now, we get off that wagon and get nothing, when we decide to buy it again in 5 years (because it is the plane we need)
