20世纪90年代初,几乎世界上每家飞机制造商都想建造“超大型喷气式客机”——下一代长距离、大载客容量(载客多达800人)的大型客机。当时有多种计划,全部都针对B747,希望替代其成为大型客机目录顶端位置,虽然没有确定这样一种新飞机是否必须比B747更大、更快或者飞得更远,但是? In the early 1990s, almost every aircraft manufacturer in the world wanted to build a “very large jetliner,” the next generation of large passenger aircraft with long passenger capacity (carrying up to 800 passengers). There were various plans for the time, all aimed at the B747 in the hope of replacing it as a top-of-the-plane location for large airliners, although it was not certain whether such a new aircraft would have to be bigger, faster or farther than the B747?
