About a year ago I applied for this program. I never heard back, my guess is that the flight was canceled for whatever reason. I checked the website just out of curiosity and it looks like they're trying to do it again. It's a pricey way to build multi time, but I imagine you would learn a heck of a lot more on a trip like that than you would flying circles around your local airport. Kind of makes we wish I didn't already have a flying job. I could talk myself into this pretty easily.
