Boeing 747-8 Freighter First Delivery Set for Sept. 19". Boeing. Archived from the original on September 24, 2011 . Retrieved September 7, 2011. In 2000, Boeing offered the 747X and 747X Stretch derivatives as alternatives to the Airbus A3XX. This was a more modest proposal than the previous −500X and −600X. The 747X would increase the 747's wingspan to 229ft (69.8m) by adding a segment at the root. [2] The 747X was to carry 430 passengers up to 8,700nmi (16,100km; 10,000mi). The 747X Stretch would be extended to 263ft (80.2m) long, allowing it to carry 500 passengers up to 7,800nmi (14,400km; 9,000mi). [2] However, the 747X family was unable to attract enough interest to enter production. Some of the ideas developed for the 747X were used on the 747-400ER. [3] Other customers found that one of the selling points of the aircraft – that it would cost less to operate because it could carry more passengers – was only true when the plane was fully loaded. A 747 that was 70% full still burned almost as much fuel as one full to capacity.

In 1968 the Boeing 747 began its first test flights, and a year later the plane flew its first official flight. In addition to these specifications, it’s also important to consider the level of experience required to operate a Boeing 747 RC plane. While some models are suitable for beginners, others may require more advanced flying skills and knowledge.

Evergreen 747 Supertanker: Global SuperTankers has converted an ex-Japan Airlines 747-400BCF for use as an airborne firefighter, serving as the second generation 747 Supertanker. The converted water bomber carries 19,600 US gallons (74,190L) of water or chemical fire retardant in eight pressurized tanks. The United States Forest Service was considering the use of this aircraft in 2017. [66] Global SuperTanker received FAA certification September 12, 2016. [67] KLM was the last 747-400M operator. The Boeing 747-400M was initially planned to be retired by January 1, 2021, however the Boeing 747-400M was instead retired by March 27, 2020, as Air France-KLM announced in early March 2020 to retire all remaining passenger Boeing 747-400s of KLM (including all KLM Boeing 747-400M aircraft) immediately due to reduced air travel demand caused by the COVID-19 pandemic, although, due to a global shortage in air cargo capacity, three KLM 747-400Ms were temporarily reactivated after just a week to operate cargo-only flights to Asia. The world's most stunning remote locations revealed in lavish photo book - from spellbinding Cornish beaches to a crooked forest in Denmark and jaw-dropping mountains in the U.S G-CIVB, the third of three 747-400 retrojets formerly operated by British Airways, is on display at Cotswold Airport in Kemble, Gloucestershire in the United Kingdom. The aircraft, which was the joint last of BA's 747-400s to leave London Heathrow alongside G-CIVY, arrived at Kemble on 8 October 2020. G-CIVB is decorated with the Negus livery used by the airline during the 1970s and early 1980s, and has been modified for use as an events centre.
