On 27 January 1986, the Airbus Industrie Supervisory Board held a meeting in Munich, West Germany, after which board-chairman Franz Josef Strauß released a statement, "Airbus Industrie is now in a position to finalise the detailed technical definition of the TA9, which is now officially designated the A330, and the TA11, now called the A340, with potential launch customer airlines, and to discuss with them the terms and conditions for launch commitments". The designations were originally reversed because the airlines believed it illogical for a two-engine jet airliner to have a "4" in its name, whilst a quad-jet would not. On 12 May 1986, Airbus dispatched fresh sale proposals to five prospective airlines including Lufthansa and Swissair.
