NPR ended production of Tell Me More on August 1st. We're sorry to see this great program come to an end, but we're glad to learn that host Michel Martin will continue at NPR. Her reporting will be part of Morning Edition and All Things Considered as well as online and at public events. With the end of Tell Me More, we have an opportunity to bring more international news to our weekday line-up.

  This time on The Engineer's Corner, I want to look back three weeks ago, and look back over fifty years ago.  And how little typos can have a big impact when it comes to engineering.
