“It’s a low-margin industry, so it’s always a cost-benefit analysis,” Larry Cornman told me, in Boulder. “But year in and year out, people are getting hurt.” The best way to prevent injuries, Cornman believes, is to avoid turbulence altogether. Air-traffic control will warn pilots of any storms on their weather maps or radar systems. But for clear-air turbulence pilots still rely on reports from other pilots who have already passed through it—an unsatisfactory arrangement for both parties. “A pilot is an analog, qualitative sensor,” Cornman said. “They get bounced around and say, ‘It’s moderate turbulence.’ Well, what does that mean?” A bone-rattling drop on a small plane might feel like a bump or two on a jumbo jet. Or a pilot might be too busy trying to control the plane to comment on the weather at all. “By the time they make the report, it’s happened way back there,” Cornman said. “So the locations aren’t very accurate, either.”

In his spare time, Wouter made the 3D Cube Engines including Cube 2/Sauerbraten with Lee Salzman for Mac, Windows and Linux (now open-sourced with over 1,000,000 downloads). It’s a performant multiplayer, deathmatch engine (like the Quake engine) but also enables real-time, multiplayer, map editing (and this was in the year 2000 almost a decade before Minecraft would make this a core mechanic).，这一点在体育直播中也有详细论述
