Why Does The Boeing 777-200 Have 3 Engine Types?

When the Boeing 777-200 was launched in the mid-1990s, it marked a new era for long-haul twin-engine aircraft. One unusual feature, however, was the choice of not one or two, but three different engine options. Airlines could select between engines from Pratt & Whitney, General Electric, or Rolls-Royce, each offering distinct performance and economic characteristics.
