The Boeing 787 Dreamliner is a long-range, mid-size wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. Here is detailed information about the Dreamliner:
Development and History
- Conception: The project to develop a more efficient aircraft began in 2003, aiming to replace the Boeing 767 and compete with the Airbus A330.
- First Flight: The first Boeing 787 Dreamliner took to the skies on December 15, 2009.
- Service Entry: It entered service with All Nippon Airways on October 26, 2011.
- Development Challenges: The program faced numerous delays due to supply chain issues, manufacturing defects, and certification problems, with initial delivery dates pushed back several times from the original 2008 timeline.
Design and Features
- Materials: The 787 makes extensive use of composite materials in its construction, which contribute to weight savings and increased fuel efficiency.
- Engines: Two engine options are available, the General Electric GEnx or the Rolls-Royce Trent 1000.
- Range and Efficiency: The aircraft boasts a range of up to 7,635 nautical miles (14,140 km) with a maximum fuel efficiency of 20% better than similarly sized aircraft.
- Cabin Environment: The Dreamliner features larger windows, higher cabin humidity, and lower cabin altitude, which enhance passenger comfort.

Operational Performance
- Market Success: The Dreamliner has been a commercial success, with over 1,000 orders from airlines worldwide by mid-2023.
- Issues: Despite its success, the aircraft has faced some significant challenges, including battery fires leading to a three-month grounding in 2013.
Environmental Impact
- The 787 is designed to be more environmentally friendly with lower emissions due to its fuel efficiency and noise reduction technologies.
