Woah, welcome to the Wayback Machine. This is from 06, I think. Last I heard the guy had moved on to another 135 job, flying a navajo, I think.
I'm confused by those who think the flying is really all that impressive. As someone else said, I've done considerably worse/better. The only thing I objected to (as someone who could have been flying the same plane the next day) at the time was rolling it and potentially tumbling the only AI in the airplane. I don't see anything there which looks terribly "high-G", particularly compared to the thunderstorms these things fly through all the time. I don't think anyone is arguing that it was smart or cool to FILM it, though, particularly not when you film the plane with its paintjob which is a giant neon sign pointing to the operator.
In the end, I think the biggest strike against this dude was his website, which was tool-tastic.
There is a lot of fun flying at FLX. You aren't expected to do anything stupid, but being single pilot PIC, you're certainly given the opportunity. That's true of any single pilot 135 operation. If you decide to do something stupid, don't film it.
