The 777-200ER (“ER” for Extended Range), the B-market version of the -200, was originally known as the 777-200IGW for its increased gross weight. The -200ER features additional fuel capacity and an increased maximum takeoff weight (MTOW) over the -200. Aimed at international airlines operating transatlantic routes, the -200ER’s maximum range is 7,700 nautical miles (14,300 km). In addition to breaking the eastbound great circle “distance without landing” record, the -200ER also holds the record for the longest ETOPS-related emergency flight diversion (177 minutes under one engine), on a United Airlines flight carrying 255 passengers on March 17, 2003, over the Pacific Ocean.
Somebody is NOT telling the TRUTH here about this aircraft…
