Boeing’s 777-9X airplane has taken to the skies and is now the largest and longest twin-engine airliner in the world. The WH-001 took off on its maiden voyage from Paine Field outside of Seattle on Saturday morning. This new aircraft can carry 425 passengers and take routes of 7,600 nautical miles. While the new aircraft’s release and first trip was a success, critics are still skeptical following the recent grounding of Boeing’s 737MAX due to recent crashes. However, the 777-9X still has 18 months of certifications and testing before it will qualify for passenger service.
