    How Lost Radar and Silent Radios Have Upended Newark Air Travel

    by

    On a recent afternoon in Philadelphia, an air traffic controller began shouting that he had lost his radar feed for planes flying in and out of Newark Liberty International Airport.Some of his colleagues still had radar but their radios went dead, prompting frantic calls to their counterparts in New York urging them to keep their planes away from Newark’s airspace.Then, for 30 harrowing seconds until the radios came back, there was nothing more to do but hope — as they had no means of telling pilots how to avoid crashing their planes into one another.Shortly after that, one controller discovered a trainee, who had been directing Newark traffic under supervision just moments earlier, shaking in the hallway.That was the chaotic scene on Monday, April 28, according to several people who were present when controllers working the airspace for Newark lost the means to do their jobs.The failure of the system the controllers rely on left several of those on duty that day with extreme anxiety, requiring a mental health respite that has caused low staffing levels for days since. It has also prompted more than 1,000 flights at one of the nation’s busiest airports to be canceled or delayed, leaving some passengers feeling frustrated and abandoned.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Michael Valentine, 74, Who Helped Drivers Stay Under the Radar, Dies

      by

      An engineer who loved to drive fast, he helped build an industry-altering device that made its debut after the national speed limit of 55 m.p.h. became law.Michael Valentine, an electrical engineer, loved to drive fast in his MGB sports car. But in 1974, after a national highway speed limit of 55 miles per hour was mandated as a fuel conservation measure, he believed that a “holy war” had begun: speed-seeking drivers against police officers trying to snare them with radar guns.“In a holy war, you can take either side and be right,” he told The Cincinnati Enquirer in 1981. “The problem,” he said, “is that police radar is an electronic device of fallible character in the hands of ordinary human beings.”Mr. Valentine, who didn’t believe that road safety was determined by finite speed limits, went into battle armed with the Escort, a radar detector that he built with Jim Jaeger, his college friend and business partner, for their company, Cincinnati Microwave.They met with early success. In 1979, a year after the Escort’s debut, Car and Driver magazine tested 12 radar detectors and ranked it the best, “by a landslide,” for its ability to pick up the signals of police radar equipment.The rave catapulted sales. In early 1981, Cincinnati Microwave had sold 50,000 Escorts, Mr. Valentine said.He never stopped upgrading the Escort, and, after parting ways with Mr. Jaeger in 1983, he designed two generations of detectors at his own company, Valentine Research.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
