Sources say Boeing’s test flight of the 777X this week was called off after an accidental explosion.

On January 22nd, according tomedia, citing sources, Boeing will test the latest 777X later this week, depending on the weather at the time, in Seattle, the United States. In September 2019, Boeing spokesman Paul Bergman announced that the Boeing 777X load test had been suspended because of a difficult issue.

Sources say Boeing's test flight of the 777X this week was called off after an accidental explosion.

Although no details were disclosed, it was reported at the time that the test was “rolled over” because a door had failed a high-intensity stress test and an external bump explosion occurred. Perhaps to reassure the outside world and over-interpret, Boeing stressed that the level of on-site pressure was far above normal.

At the time, however, it was only a static test of the Boeing 777X, and the damage was manageable. Just as the final part of the static test, it is not known when it will resume after a pause.

The Boeing 777X is positioned as the world’s largest and most efficient twin-plane, with a dual-aisle wide-body design with a length of 70 meters and a wingspan of 72 meters. But because GE delivered the GE9X slowly, the first flight was delayed until 2020.
