In December 2014, Boeing began construction on a 367,000 sq ft (34,100 m2) composites facility in St. Louis to be completed in 2016, to build 777X parts with six autoclaves for the wing and empennage parts, starting in 2017. Its development cost was expected to exceed $5 billion with at least $2 billion for the carbon-composite wing. The design work was distributed between Charleston, Huntsville, Long Beach, Philadelphia, and St. Louis in the U.S and Moscow, Russia.

Nine different -200 customers have taken delivery of 88 aircraft, with 55 in airline service as of 2018update. The International Civil Aviation Organization (ICAO) aircraft type designator system adds a preceding manufacturer letter, in this case “B” for Boeing, hence “B772” or “B773”. The higher-thrust GE90 variants are the first production engines to feature swept rotor blades.
Latimer made the incandescent lightbulb practical by developing a carbon filament that would extend its life greatly. Thomas Edison gets most of the credit for the invention of the lightbulb, but Lewis Latimer made it practical and affordable. She became the first African American woman to hold a medical patent. Madam C.J. Walker was a self-made millionaire who transformed the beauty industry. Then, in his quest for a needle polish, he stumbled upon a formula that straightened human hair — marking his first invention.
Boeing 777
Raked wingtips were added to improve overall aerodynamic efficiency, extending each wing by 2 meters (6.5 feet). On February 14, 2019, it was reported that Etihad would take only 6 of the X airliners it had originally ordered. Emirates’ demand had been slowing and it was considering deferral of deliveries, having the smallest sovereign wealth fund backing of the Gulf carriers. Boeing acknowledged that the GE9X engine would have sufficient margin to power a stretched variant.
Some customers bemoaned the loss of engine competition, like Air Lease Corporation’s CEO Steven Udvar-Hazy who wanted a choice of engines. In the rest of 2013, thrust was bumped to 102,000 and 105,000 lbf (450 and 470 kN) to support the MTOW growing from 769,413 to 775,000 lb (349,000 to 351,534 kg) and increasing the payload-range, with a possible 108,000 lbf (480 kN) envisioned. The program has suffered from numerous delays; as of October 2025,update Boeing expects the first aircraft to be delivered in 2027. The Boeing 777X is the latest series of the long-range, wide-body, twin-engine jetliners in the Boeing 777 family from Boeing Commercial Airplanes. As of late 2023 the 777 program was launching three new aircraft every month. As of the end of 2022 Boeing had received over 2,100 orders for the 777 and had made more than 1,600 deliveries of it to some 60 customers since the 777’s introduction, making it the aircraft with the most orders and deliveries of any wide-body jetliner.

On September 5, in the presence of FAA inspectors, a door blew off on the 777X static test airframe during the ultimate load test, which is conducted with the airplane stressed and pressurized beyond normal operating limits. The company continued to target first deliveries in 2020, though it intends to boost production of current-generation 777 freighters in 2020. The 777X test plan was later revised as several months are required to develop and test fixes to the GE9X, and first flight slipped to October–November. The primary systems were installed by December and its second GE9X engine were to be hung in early 2019.
Alcorn’s research into plasma etching, for which he received a patent in 1989, is still used in the production of computer chips, also known as semiconductors. From its design to its performance, it’s changed the way we think about air travel. The cabin is spacious, the air feels fresher thanks to advanced systems, and there’s plenty of room for luggage. The 777 is a long-range jet, able to connect cities halfway across the world without refueling. Big windows and quieter engines add to the overall experience, making it a favorite for long-haul travelers.
Testing and certification
- A more profitable fleet and more satisfied passengers.
- The first flight took place on June 12, 1994, under the command of chief test pilot John E. Cashman.
- By March 2023, IAI had a backlog of over 60 orders, and completed the first flight of its prototype.
- An engineer at NASA’s Jet Propulsion Laboratory, created the Super Soaker water gun in his spare time.
- The third-generation of the 777, launched as the 777X, is to feature new GE9X engines and new composite wings with folding wingtips.
The advanced wing design of the 777 features a long span with increased thickness to dramatically improve airplane performance and reduce operating costs. On August 6, 2025, Cathay Pacific ordered an additional 14 aircraft, which brings the airline’s total commitment to 35 airframes. The deal also includes 8 spare engines plus two options and a maintenance service contract for the General Electric GE9X engines. It will seat around 426 passengers with a range of 7,285 nmi (13,500 km; 8,383 mi).
To avoid disrupting current 777 assembly, a temporary low-rate assembly line was set up for up to 38 airframes before transitioning to the main FAL in the early 2020s. In February 2018, its wing components were ready to go through assembly as Mitsubishi Heavy Industries, the 787 composite wings manufacturer, advised Boeing on the wing assembly. Boeing’s first composite wing spars, stringers, and skin panels are formed in the $1 billion Composite Wing Center before assembly on a new horizontal build line. In February 2018, Subaru (ex–Fuji Heavy Industries) completed the first aluminum and titanium center wingbox integrated with main landing gear wheel wells at its Handa factory. A major leap in automated production, it drills the tens of thousands of holes in the fuselage more quickly, accurately, and safely. Aircraft Numbers 1 and 6 were planned to be used for ground tests; four 777-9s (No. 2 to 5) were slated for the flight test and certification campaign, with two 777-8s to come later.
The aircraft features the largest landing gear and the biggest tires ever used in a commercial jetliner. Smaller folding wingtips of 11 feet (3.35 m) in length will allow 777X models to use the same airport gates and taxiways as earlier 777s. Folding wingtips reemerged as a design feature at the announcement of the upgraded 777X in 2013. In 2013, a new wing made of composite materials was introduced for the upgraded 777X, with a wider span and design features based on the 787’s wings.
He is credited with 20 inventions, eight of which he received patents for. The Super Soaker, first patented in 1986, is his most popular invention. An engineer by training, Johnson has worked on both the stealth bomber project for the Air Force and the Galileo space probe for NASA. Inventor Lonnie Johnson holds more than 80 U.S. patents, but it’s his invention of the Super Soaker toy that is perhaps his most endearing claim to fame. George Washington Carver became one of the leading agronomists of his time, pioneering numerous uses for peanuts, soybeans, and sweet potatoes.
Production
In 1922, he patented the traffic signal, introducing the third “caution” signal, now the yellow light. Became the first African American self-made millionaire by launching a line of hair products specifically for Black hair, starting with Madam Walker’s Wonderful Hair Grower in 1905. Despite not patenting the creation, the thin crisps became a global favorite snack.
- In economy class, airlines can delight passengers with premium economy comfort in a nine-abreast configuration.
- The 777 offers excellent cabin flexibility and the ability for operators to accommodate the latest in premium seats and in-flight entertainment.
- This was the largest commercial aircraft launch by dollar value with Emirates ordering 150, Qatar Airways 50, and Etihad Airways 25, in addition to the September 2013 Lufthansa commitment for 34 aircraft.
- Offering greater long-haul performance, the variant became the most widely ordered version of the aircraft through the early 2000s.
At the successful conclusion of flight testing, the 777 was awarded simultaneous airworthiness certification by the US Federal Aviation Administration (FAA) and European Joint Aviation Authorities (JAA) on April 19, 1995. The first aircraft built was used by Boeing’s nondestructive testing campaign from 1994 to 1996, and provided data for the -200ER and -300 programs. To satisfy ETOPS requirements, eight 180-minute single-engine test flights were performed. The 777 was completed with such precision that it was the first Boeing jetliner that did not require the details to be worked out on an expensive physical aircraft mock-up.
Airline planners’ requirements for larger aircraft had become increasingly specific, adding to the heightened competition among aircraft manufacturers. Under vegas casino ETOPS rules, airlines began operating the 767 on long-distance overseas routes that did not require the capacity of larger airliners. These regulations allowed twin-engine airliners to make ocean crossings at up to three hours distance from emergency diversionary airports. The mid-size 757 and 767 launched to market success, due in part to 1980s’ extended-range twin-engine operational performance standards (ETOPS) regulations governing transoceanic twinjet operations.
Scottron graduated from Cooper Union with a degree in Algebra and Engineering in 1875 and obtained a number of patents for various devices. He obtained a patent for his first invention, the Scottron Mirror, in March 1868. He was born sometime between 1841 and 1843 and moved to Florida in 1864, starting a grocery store chain. She was born in Ohio in around 1885 and later worked in New York City as a family hairdresser. His owner, Joseph Davis, also attempted to patent the device but was denied because he was not the true inventor. He was not able to patent the device because he was a slave.
In designing the 777 as its first fly-by-wire commercial aircraft, Boeing decided to retain conventional control yokes rather than change to sidestick controllers as used in many fly-by-wire fighter aircraft and in many Airbus airliners. Both models are to be equipped with new generation GE9X engines and feature new composite wings with folding wingtips. The is a further stretched variant with a capacity of over 400 passengers and a range of over 8,200 nmi (15,200 km; 9,400 mi), whereas the is slated to seat approximately 350 passengers and have a range of over 9,300 nmi (17,200 km; 10,700 mi).
Airplanes can be shifted within a network while maintaining timetables, keeping profit margins strong, and satisfying high passenger expectations. More than an aesthetic triumph, the wide 777 cabin is designed to increase revenue potential and improve profit performance. On board connectivity also enables passengers to stream media content to their personal electronic devices (PED).
