TMZ has obtained a photo and video shot by Chris Baker, former Blink-182 drummer Travis Barker's assistant, just moments before he boarded the Learjet with Barker and DJ AM that crashed on takeoff. Baker sent the cell phone photo of himself at 11:22 ET, 31 minutes before the plane went down. Baker e-mailed the photo to a friend with the text, "Go hard on the block." The video of the jet was shot by Baker shortly before he boarded. Bakerwas one of four people who died in the crash. Barker and DJ AM (born Adam Goldstein) miraculously survived.
