Encore, encore

"I called out Sue's name twice, and the second time she raised her hand," he said. "I announced we had to get her to Pittsburgh, to the children's hospital, that they had a heart for her little boy." - Pennsylvania State Police

That is an excerpt from this Fox News article about a boy getting an opportunity at life from a live saving organ donor but also, because of technology. They were at a concert and his mother had a cell phone that was able to be located from GPS, but I think it was triangulation. GPS is a receiver, cell phones send out signals that can be triangulated.

If the venue that she was at had a cell phone jammer (which is illegal right now in the US but some want to change that) or if her phone was turned off, he may have missed an opportunity at a new heart.

The important thing is the fact that someone donated their heart to John.
