I've long known Alfas weren't all that much rustier than their contemporaries. What I didn't count on was their being less rusty than bazillion-dollar stealth aircraft. Every time you think the defense contract business couldn't get any more f-ed up, you're proven wrong again.
And yes, I know rust is a specific sort of corrosion not associated with the metals used in an F-22. Pendantic isn't something you hang around your neck, ya know?
