 After last week's show, as Mary and I, you know, we headed down to Dallas, our driver who was taking us down there, Larry, he's a super passionate guy about aircraft and aviation. We had a good conversation with him and tried to answer some of his questions. So, like me, one of his favorite planes, it's the Boeing 757. But that plane was designed in the 1970s. It took flight in the early 80s. It ended production 20 years ago in 2004. There's been no replacement of that jet. Clearly, it was successful.
