One could attribute at least one accident to lack of auto wing sweep.
I think that's being a little too lenient - cognitive failures tend to account for this type of accident, not the presence of the 'technology' (I use the term loosely here) in question.
It's like saying that a recent Harrier crash was exacerbated by the presence of the nozzle lever.
People used to make too much of the WS on the Tornado (I'm sure they still do). It's just like a gear stick. One position to go fast and straight (63/67), one to go slow and be 'vaguely' manoeuverable (25) and one in the middle (45).
(And a hidden 4th one that reputedly gives better mpg!)
