History is full of "Multi Role" aircraft from the BF110, to the F111, which although able to fill multi roles did none of them well, the F35 will Im afraid be another example of this, as to flying a S/E fighter in our climate and geography it looks like we didnt learn much from the 104 experience. The very high per unit cost of the aircraft will make our present crop of senior military brass reluctant to employ them to their limits, to bend one will not be a career enhancing move for sure.There are aircraft out there costing much less and just as good, {which also function in minus 45} however the ghosts of the Cold War still linger in the coridors of Ottawa and NDHQ, one only has to look at the C17 purchase to see this, now of course if offered say fifty hours on type I might change my view!
