The Boeing 767 family is a complete family of airplanes providing airlines with maximum versatility in the 200 to 300-seat market. It includes three passenger models - the 767-200ER, 767-300ER and 767-400ER - and a freighter, which is based on the 767-300ER fuselage. The 767-200ER has a range of more than 7,500 miles and the 767-300 freighter can haul 60 tons more than 3,700 miles. In 1997, Boeing launched the 767-400ER, which can take 304 passengers more than 7,000 miles. Military versions include the 767 AWACS, which first flew Aug. 9, 1996, and the 767 tanker/transport, launched in 2000, designed to replace the aging KC-135 aerial tankers..
