In which country the world’s first 16-megawatt offshore wind turbine has been successfully installed?

Boeing, the US-based aerospace company, has successfully completed the first test flight of 777X, the world’s largest twin-engine aircraft. The test has been conducted at a time when Boeing is trying to rebuild its tarnished image after two fatal crashes of the 737 Max aircraft which killed nearly 350 people in the last two years. 777X’s maiden flight took off from a Boeing field in Seattle, Washington, and flew for 3 hours and 51 minutes before landing back at the starting point. According to Boeing, the 777X is 252 feet long and extends 235 feet from its wingtips. It has gigantic GE9X engines that exert about 10,000 pounds of thrust. 777X offers 10% better fuel efficiency than its nearest rival Airbus A350-1000 which seats 360 passengers. The maiden flight, also known as first flight, of an aircraft is the first occasion on which an aircraft leaves the ground under its own power. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved.
