In the case of the Swiss air crash it was a combination of a mis-set altimeter alignment, plus poorly trained controllers misdirecting pilots into mountainous terrain when an opposite turn to an alternate downwind approach was required. One other famous incident occurred when the automatic landing control was not disengaged, a corporate culture of requiring steep climbs out of this one airport for noise abatement, and an automatic misread of an updraft as if it was a landing flare stall, which cut out the engines during takeoff.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
