Upon closer inspection, the aircraft is sporting a Rolls-Royce engine on the #2 pylon. When P&W launced the PW2000 in 1979, Boeing pressured RR to supply a more competitive engine for the 757. |Developed from the more advanced -524, the company produced the 40,100 lbf (178,000 N) thrust RB211-535E4, which entered service in October 1984. While not as efficient as the PW2037, it was more reliable and quieter. After a large order from American Airlines in May 1988, popularity took off and the engine continued to dominate the 757 market. Photo from Boeing
