CH-46 simulator:
The purpose for me coming back to the states in the middle of my year abroad was to get through helicopter refresher training as expeditiously as possible. It's faster to get through in Feb-Mar than July-Aug.
I know many of my Indonesian friends didn't believe me when i told them i'm a helicopter pilot. "Sure,,, spy" ha ha.
well this is what i do for a living... and what a part of my training looks like! my other day job.
