the european industry began to accept, along with their governments, that collaboration was required to develop such an aircraft and to compete with the more powerful us manufacturers. negotiations began over a european collaborative approach and at the 1965 paris air show the major european airlines informally discussed their requirements for a new "airbus" capable of transporting 100 or more passengers over short to medium distances at a low cost. the same year hawker siddeley (at the urging of the uk government) teamed with breguet and nord to study airbus designs. the hawker siddeley/breguet/nord group's hbn 100 became the basis for the continuation of the project. by 1966 the partners were sud aviation, later aérospatiale (france), arbeitsgemeinschaft airbus, later deutsche airbus (west germany) and hawker siddeley (uk). a request for funding was made to the three governments in october 1966. on 25 july 1967, the three governments agreed to proceed with the proposal.
