I'd bet it was him. He has some type of post stabilization that has a unique look about it, and this matches that pretty well.
i'd guess someone who works at Genentech. It doesn't really sell Genentech that much so I couldn't see them paying for it. Having the access the person did though suggests they either work there or did the video for free as a way to build their resume.
MMmm its still a tad riskay IMO and not that professional as the airframe is in shot time and time again.. anyhow just wondered if the pilot was on here or known by anyone on here.. the more I look at it the more I am thinking employee doing a boss a favour.. BTW looking at other vids on there what is an internship? is it where you work for nowt funded by your parents to get work experience?
