“Queen of The Skies,” “jumbo jet,” many years on, the 7 4 7 remains an iconic plane with its distinctive hump, is the most recognizable plane in the sky, and has always been a passionate favorite of aviation enthusiasts. During its development, this aircraft has undergone transformations to suit its ability to carry people, goods, and other government purposes. There are variations that have been applied and become popular, but there are also variations that only stay on paper. Unreleased! Boeing 747s production FAILED. Here's Why
So which Boeing 7 4 7 hasn't been released yet? Why did Boeing stop production of the Boeing 7 4 7? What is the reason behind this? let's dive in!
In the late 60 and early 70, Boeing researched to develop a shorter 7 4 7 with three engines, with the sole purpose of competing with smaller aircraft like the Lockheed L -1011 TriStar and McDonnell Douglas DC-10. Unreleased! Boeing 747s production FAILED. Here's Why. The center engine would have been fitted in the tail with an S-duct intake similar to the L-1011's. Overall, the 7 4 7 trijet would have had more payload, range, and passenger capacity than both of them. But there 2 main issues that led to the idea's eventual rejection. The first was the engineering needed to build this new aircraft. To be structurally sound, this new aircraft would have needed to have a whole new wing designed for it. This is due to the fact that contemporary wing designs were developed with two engines per side. The requirements for pilot training were the second factor in the project's failure. Boeing was making an effort to produce a product that was almost exactly the same as its typical 7 4 7 offerings. Unreleased! Boeing 747s production FAILED. Here's Why. They sought to keep the current handling qualities while converting to a three-engine configuration so that minimal training would be needed. This proved challenging for the company to do. Therefore, they were not able to pursue the Trijet project to the end but returned to the shortened quadjet type that we know today as the 7 4 7 Short Performance.
In January 1986, Boeing first announced plans to develop a larger ultra-long-haul variant, the 7 4 7 -500. The aircraft was supposed to go into service in the mid-to-late 1990. The generator would use an engine developed from General Electric's propfan technology, but the engine would be shrouded, have a bypass ratio of 15 to 20, and have a propfan diameter of 10 to 12 feet. Airlines will be able to operate nonstop flights between Sydney, Australia, and London, England thanks to the aircraft's extended length (including the upper deck), improved wings that minimize drag, and the ability to fly quicker and cover a greater distance. Unreleased! Boeing 747s production FAILED. Here's Why
Boeing announced the 7 4 7 A S B (Advanced Short Body) in 1986 as a response to the Airbus A3 40 and the McDonnell Douglas MD-11. With this aircraft design, the 7 4 7 SP fuselage would have been shorter and the sophisticated technology from the 7 4 7 -400 would have been combined. The aircraft had a range of 8,000 nautical miles (9,200 miles; 15,000 kilometers) and was intended to accommodate 295 passengers. Nevertheless, the project was shelved in 1988 in favor of the Boeing triple 7 since airlines showed no interest in it.

the SP = Special Performance not "short performance"

thanks for your feedback, my bad!

747 failed????
Then why is there over 1500 built??? 🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔

Oh Dear these AI voice overs "one thousand nine hundred eighty" "one thousand nine hundred ninety" omitting the word "Point"
