You didn't read this article and you know nothing about Jet Turbines.
True story...one of the first jet turbined helicopters worked so well at altitude they had to wait until it had run out of fuel to land it, why because the higher you go the better a Jet turbine works.
That's a no brainer, jets work better the higher they fly, anyone that knows anything about aircraft knows that so you saying that the MV-22 can't land in the vertical at elevation is just another attempt to smear it and it's capabilities.
And to actually suggest that A Marine Corps Aircraft could never be equipped with ANY WEAPONS at all is down right silly. It already has provisions for 2 50 calibers as well as two hard points for external stores. built into it at the factory. Even the CH-46 doesn't have hard points for external stores.
just that I have some classmates and friends that are "Thunder Chickens" and would hate to have to go to any more funerals.
