How do you take a 235-ton Boeing 777 from zero to 60 in six seconds? With the world's most powerful jet engine, the new General Electric GE90-115B, dwarfing Boeing technician Jeff Adamson. Quantum leaps beyond the firstjet engines of the late 1930s, the GE90 churns out 150 times their thrust and could suck all the air out of Madison Square Garden in two minutes. With a fan built of weight-saving composites, the GE90 will soon power extended-range 777s on flights up to 18 hours.
