The first large made-in-China passenger plane successfully completed its maiden test flight Friday, marking a key milestone on the country's ambitious journey to compete with the world's leading aircraft makers.
The narrow-body C919 jet -- white with green and blue stripes -- disappeared into the clouds after taking off from Pudong international airport in the commercial hub Shanghai as a crowd of thousands cheered, including top officials.
It successfully landed some 80 minutes later and the five-member crew was handed flowers, with captain Cai Jun describing the flight as "very satisfactory."
Built by state-owned aerospace manufacturer Commercial Aircraft Corporation of China (COMAC), the plane represents nearly a decade of effort in a government-mandated drive to reduce dependence on European consortium Airbus and US aerospace giant Boeing.
"China's big commercial jet project made a huge breakthrough. It is a major milestone of China’s aviation market," China's State Council said in a statement.
State media said the plane flew at an altitude of around 3,000 metres (9,800 feet), some 7,000 metres lower than a regular trip, and at a speed of more than 300 kilometres (186 miles) per hour.
While delayed since last year, the flight is the latest sign of China's growing ambition and technical skill, coming one week after the country launched its first domestically made aircraft carrier and docked a cargo spacecraft with an orbiting space lab.
China has dreamt of building its own civil aircraft since the 1970s, when it began work on the narrow-body Y-10, which was eventually deemed unviable and never entered service.
- $1 trillion market -
President Xi Jinping himself has endorsed the new project.
His call to arms is emblazoned on the wall of the jet's production facility: "Accelerate the construction of the world's top aviation company and continue to make new contributions to develop a strong aviation industry."
China is a massive battleground for Boeing and Airbus, with the country's travel market expected to surpass the United States by 2024, according to the International Air Transport Association.
Airbus and Boeing estimate that Chinese airlines will need between 6,000-6,800 aircraft at a total price of around $1 trillion.
Both companies congratulated COMAC on the flight.
The twin-engine C919, whose name sounds like the Chinese word for "everlasting", can seat 168 passengers in an arrangement similar to other narrow-body jets: three white-velvet upholstered seats line each side of its central aisle.
It has a range of 5,555 kilometres (3,444 miles) and has received 570 orders, almost all from domestic airlines.
COMAC made two planes for the test flight and it expects to produce four more by 2019, said Bao Pengli, deputy head of Shanghai Aircraft Manufacturing Co., COMAC's production arm.
The Shanghai-based firm aims to become one of the world's leading civil aircraft manufacturer in the next three years, seeking to have the C919 and its ARJ21, a smaller 90-seat regional jet, both certified to fly internationally.
But it will be sometime before the C919 is ready to compete with the top-selling products of the world's aviation giants, said Bao.
"The biggest challenge is that the whole manufacturing experience still needs improvement because this is the first time China is making a primary route plane," Bao said.
- Earning trust -
The C919 will need to pass more tests to obtain Chinese airworthiness certification and COMAC hopes to get the green light from US and European regulators.
The ARJ21 plane, which entered service in 2016, several years late, is currently restricted to flying domestic routes as it still lacks the US Federal Aviation Administration (FAA) certification.
Another challenge for the C919 is earning consumers' trust, said Shukor Yusof, an analyst with Malaysia-based aviation consultancy Endau Analytics.
"It will take some time for customers around the world to be comfortable buying Chinese airplanes," he said, adding, "it's not going to happen in the next 10 years."
"It's going to be incredibly tough not because it's not a good product. But because you need to get comfort and credibility to the product among potential clients, potential customers."
