It was obvious from the start he was not a journalist. His articles were thorough, technically flawless and exhibited the same kind of skepticism of officialdom that most of us on the list shared. If reporters in the mainstream media had even a fraction of Zehr's engineering background the FBI's TWA 800 investigation might well have taken a different tack.
Whether it was the Foster "suicide," Flight 800 or the Clinton administration pulling the wool over innocent reporters and Republicans with one of its proposals, we could count on Ed Zehr to sort out truth from fiction. I particularly appreciate his thorough debunking of the CIA's explanation for Flight 800's alleged 3000-foot climb after the explosion. Nobody else had both the engineering background and a willingness to challenge the establishment on this, sadly. Zehr's well-written but technical articles on Flight 800 were read by maybe 800 people, understood by far fewer.
He will be hard to replace. May he rest in peace.
