I’m not sure why this is news.
When I came back from visiting Asia, the jet stream propelled the plane to 810 or 815 mph ground speed. I knew because I like to watch the flight map on the in-flight entertainment. It was pretty awesome to know we were traveling so fast but not, I think, newsworthy.
Its news for those of us that have an interest, were or are in aviation. No interest than move along nothing for you to see.
