Initially considered as an improved Boeing 727, the company determined that it was more economical to design an entirely new airplane. Along with the Model 767, which was developed concurrently, it was the first airliner produced with a “glass cockpit,” in which data is displayed on electronic screens rather than mechanical instruments.
The Boeing 757-200 is a twin-engine, medium-sized airliner intended for short or medium length routes. It is operated by two pilots and can carry up to 239 passengers.
The 757-200 is 155 feet, 3 inches (47.320 meters) long, with a wingspan of 124 feet, 10 inches (38.049 meters) and overall height of 44 feet, 6 inches (13.564 meters). The airliner has an empty weight of 127,520 pounds (57,842 kilograms) and a maximum takeoff weight of 255,000 pounds (115,666 kilograms).

Production aircraft were available with either Rolls-Royce RB.211-535E or Pratt & Whitney PW2037 engines, with thrust as high as 43,734 pounds (194.54 kilonewtons) per engine.
The Boeing 757 has a cruise speed of 0.8 Mach (530 miles per hour, or 853 kilometers per hour) at 35,000 feet (10,668 meters). The service ceiling is 42,000 feet (12,802 meters). Its maximum range is 4,718 nautical miles (7,593 kilometers).
The Model 757 was produced from 1981 to 2004 in both passenger and freighter variants, or a combination. 1,050 Boeing 757s were built.
The first 757, N757A, remains in service with Boeing. The airplane has been radically modified as an electronics test bed.

Noticed a drouge at the tip of the tail. I’ve not noticed that before on ther test flights. Do you know the purpose?
I saw the drogue ‘chute, too, Ernest, but no, I don’t know its purpose.
NASA refers to it as a “Trailing Static” or “Trailing Cone”. See pages 8 through 10 of NASA Technical Memorandum 104316, Airdata Measurement and Calibration. (Google brings it up.) Thanks for your work on these histories.
Thank you. 🙂
That is called a trailing cone, it is drug behind the aircraft to collect a second air data source from clean air, to validate the primary sources that are part of the aircraft systems. It retracts and extends to that is is several hundred feet behind the plane in flight.
Thanks!
The cone is connected to tubing on a reel system so it can be deployed behind the aircraft to provide a static pressure measurement that is used to determine the production pitot static system’s static source position error. Boeing uses this system on all their commercial and commercial derivative military test aircraft. The alternate is to install nose or wing boom on the aircraft.
Thank you, Kevin.
