A few years ago, Cornman found a way around the problem. In the U.S., commercial flights served by air-traffic control—some twenty-seven thousand a day—are required to transmit their position, altitude, and velocity. By tracking those transmissions and the planes’ motions over time, a new program that Cornman developed at NCAR can create a moment-by-moment snapshot of turbulence as it’s happening. The F.A.A. is planning to test the program this year. Together with NCAR’s earlier software, Sharman’s forecasting models, and data from radar arrays on the ground, this system could start to give pilots the advance warning they need. “That is the future for me,” Cornman said. “All these operations get integrated in a seamless network. The pilots don’t have to talk to air-traffic control and say, ‘Should I go up or down?’ They just get a display with a color-coded flight track on it. And they see that it looks better a few thousand feet up.”
This concluded my business with Zero Email, and so the next step was removing it from my account. I get emails with non-disclosure agreements and embargoed information all the time, and while Zero Email’s privacy policy doesn’t raise any immediate red flags, this is information that people would be displeased to have leaked, and so, I try to keep the number of services connected to my Gmail at a minimum, even if the company promises it’s not reading my data.
