From an ebay auction, a 1966 Boeing cutaway drawing of the early swing-wing version of the 2707 SST. While the wing would have made low speed flight, in particular takeoffs and landings, more efficient and comfortable, the technology of the time would have made the wing pivot and associated systems simply too heavy and complex for a commercial system such as this. Thus the final 2707-300 SST did away with the variable geometry wing.
But damn if it wasn’t sexy.
