Pratt & Whitney's uniquely configured Boeing 747SP recently made its debut as the industry's newest engine flying testbed with Pratt & Whitney Canada's PW308C, and is now flying the PW1200G for the Mitsubishi Regional Jet.

In addition, Pratt is flight-testing its second geared turbofan model (see p. 39). Spencer Sloan/Pratt & Whitney photo.
