I'm not a Marine, but I've had my fair share of Osprey rides. Kind of catches you off guard the first time you take off. Taxi, taxi, taxi, and off and up like a rocket. When you take off in a helo, that foward flare kind of negates any g's that might thow you backwards. Not so with the Osprey. Hang on to something. I'd be lying if I said my asshole wasn't puckered on my first ride with all the negative press it had in the testing phase.
For Cayenne's comments, I don't know about jungle stuff. Everywhere I've been in the jungle, the rotary aviation platforms were either host nation or contracted. The Osprey doesn't fall into either of those categories. For insertion, it does have FRIES capability. I would assume that a unit could conduct a SPIES extraction with this as well, but I haven't heard of anyone doing SPIES in today's full battle rattle (anyone else want to chime in on that?).
