The Boeing 757 is often praised for its impressive performance—powerful engines, a relatively lightweight structure, excellent climb rates, and highly efficient aerodynamics. But from an airline economics perspective, the story is more complicated. The 757 is essentially a narrow-body revenue generator with wide-body operating expenses: wide-body wings, engines, landing...

The MD-11 has always had a critical design flaw. It was manageable until someone screwed up. To improve fuel efficiency and range, its horizontal stabilizer was made smaller than those of earlier DC-10 variants. While the design delivered performance benefits, it also reduced the aircraft's natural pitch stability, particularly at slower speeds during approach and landing. To help compensate, the MD-11 relied heavily on computerized stability augmentation systems. Many crews also preferred flying slightly faster approaches, which improved pitch stability but could make the aircraft more challenging to manage during touchdown due to its weight and sensitivity in roll and yaw. These characteristics became evident in several high-profile accidents. In 1997, a FedEx MD-11 arriving at Newark was reportedly operating under the belief that runway length was limited, prompting the crew to aim for an immediate touchdown. The aircraft landed hard, bounced, and became unstable. Instead of executing a go-around, attempts to salvage the landing resulted in another severe impact, collapsing the landing gear and destroying the aircraft in a post-crash fire. All five crew members survived. The accident highlighted a key lesson: when an MD-11 bounced significantly after touchdown, a go-around was often the safest option. That lesson resurfaced in tragic fashion in 2009 at Narita, Japan. During strong and gusty crosswinds, a FedEx MD-11 touched down hard and bounced. Believing the aircraft could still be recovered onto the runway, the crew attempted to continue the landing. The resulting control inputs led to an even harder impact, loss of control, and a crash that destroyed the aircraft and claimed the lives of both pilots. 📹: buybygb

The Convair 880, a remarkable yet underappreciated jet airliner in aviation history, completed its final flight in 1991, nearly two decades after its commercial retirement in 1973. Manufactured by Convair, a division of General Dynamics based in the United States, this sleek aircraft was designed to compete with industry giants like the Boeing 707 and Douglas DC-8. Introduced in 1959, the Convair 880 was celebrated for its impressive cruising speed of approximately 615 mph (990 km/h), making it one of the fastest commercial jetliners of its era, capable of rivaling or even surpassing the Boeing 707 in speed. Powered by four General Electric CJ805-3 turbojet engines, it was engineered for efficiency and performance, with a range of about 3,000 miles (4,800 km) and a capacity to carry up to 110 passengers in a typical configuration. Despite its technological achievements, the Convair 880 faced significant challenges. High operating costs, driven by its fuel-hungry engines, and fierce competition from more economical and versatile rivals limited its market success. Production ceased in 1962 after a brief six-year run, with only 65 units built—a stark contrast to the hundreds of Boeing 707s and DC-8s produced. The aircraft primarily served major U.S. carriers like TWA, Delta, and United, but its high costs led to its gradual phase-out by the early 1970s. The final flight in 1991, departing from the Mojave Air and Space Port in California, marked the end of the Convair 880’s operational life, as it was retired to storage or scrapped. Today, the Convair 880 is a rare relic of aviation’s jet age, with only a handful of airframes preserved. Notable examples include one displayed at the Delta Flight Museum in Atlanta and another in private hands, occasionally used for film productions or as a static display. Its sleek, narrow-body design and historical significance as a symbol of the early jet era make the Convair 880 a cherished piece of aviation heritage, though its limited production and short service life render it a largely forgotten gem in the shadow of its more successful competitors.

Rare visuals of a "Tail cone evacuation slide" in action when a Delta Airlines Boeing 717, which departed Atlanta for Columbia, South Carolina, returned back after smoke filled the cabin mid-flight, prompting a safe evacuation. The tail slide on the Boeing 717 got deployed after the rear cone was Jettisoned from the fuselage. Some of the aircraft like MD-83 & B717 have a tail cone emergency exit in the tail cone at the aft end of the passenger cabin. How does tail cone emergency slide work? -If the emergency exits are armed & the handle located in the door of the aft passenger entrance is actuated, the tail cone detaches & the slide deploys automatically. -On actuation, the tail cone releases & falls. It then turns 90° & moves to the left side of the aircraft to keep the tail cone from interfering with the deployment of the slide. -Jettison & slide deploy uses a set of clasps & cables which are attached to a bar on the door & to the clamping bolts on the tail cone. -The tailcone exit may be actuated from two more locations, 👉 A handle on the inside of the tail cone (non-pressurized area). 👉 Another handle on the outside of the aircraft. -The Boeing 717 twin-engine airliner produced by Boeing Commercial Airplanes was developed for the 100-seat market and originally marketed by McDonnell Douglas in the early 1990s as the MD-95 until the company merged with Boeing in August 1997.
