I'd just like to see a little more efficiency applied to the armed forces... I mean, hell, why can't we use that %#!$ Harrier, instead of reinventing the wheel with that POS Osprey, which will probably kill more soldiers than the enemy ever will...

Well for one, the Harrier is a fighter/bomber. The Osprey is designed for transport. For another, the Osprey is on the leading edge of a new type of design, as different from existing models as helicopters are from fixed-wing. You have to expect problems with a new technology, but I doubt the complexity involved is any more insurmountable than the first helicopters seemed at the time.
