I was walking down the isle of a hypersonic jet and saw my lab manger and the sterility supervisor in business class. The jet was set up with a lounge on the upper level. The pilot’s seat at the front of this section and were not segregated from the rest of the craft. The window was huge and we were flying around 50-100 m above the ground. Apparently we were heading towards Paris , though it looked like no Paris I had ever seen. The dream ended as I saw the landing strip appear and we began to land.
