This modified Boeing 747SP is one of two used to flight test Pratt & Whitney and Pratt & Whitney Canada engines. It landed in Iqaluit, Nunavut, Canada, on March 5 and was deliberately left outside overnight in frigid temperatures. These crucial steps in the engine testing process expose it to environmental conditions impossible to simulate during local ground testing. [Credit: Pierre Trépanier, P&WC Flight Operations]
