In 1965 Boeing put together a design team to work on the new airliner which was already given the Boeing 747 designation. The proposal Boeing had put forward for the military transport, the CX-HLS, was taken as a start point. Some features were retained, but others such as the high wing design were discarded. The design also had to be future proof. At this time in aviation, it was felt that supersonic travel had every chance of becoming the norm, so Boeing had to take an each way bet. The design team for the Boeing 747 had to come up with an aircraft that met the requirements of airlines who wanted mass passenger movement, but at the same time had the ability to be an effective freighter.
