"[Leadership] is what Joe and the military structure brought to Project Excelsior," says Ryan, who also co-write Kittinger's recent autobiography, Come Up and Get Me. Kittinger has applied similar discipline to Red Bull Stratos. During a recent press briefing, Thompson had this to say: "We've got an incredible team of scientists and engineers who put together this program, and I don't think there's anybody who worked as hard as Joe. He sits in the capsule sometimes for hours, just thinking through the process, looking at the switch panels, looking at the instrumentation, making notes. He comes back and says, 'Art, we need to change line 32.' Joe's been amazing at taking all of his experience and expertise and combining them to really help Stratos happen."
