The video quality is poor, but the content is interesting. A mid-1960’s promotional film for the US SST program (Boeing 2707), focusing on the economic benefits. A lot more reference to *gold* than you would see these days, and a lot more worry about the economic dominance of Concorde than reality would end up providing.
That first generation of SST’s almost certainly never stood a chance of being economically successful. The Boeing 2707 would very probably not have been the economic disaster that the Concorde was, but the oil crisis of the 1970’s and inability to fly overland routes almost certainly would have wrecked its ability to be profitable. However… a *next* generation of SST built on the lessons of the 2707? *Possibly* quite successful.
