Yeah, that's old fashioned. A fully loaded 747 flying at cruising altitude will be able to go between 108 and 144 miles before landing if all the engines sudden

Yeah, that's old fashioned. A fully loaded 747 flying at cruising altitude will be able to go between 108 and 144 miles before landing if all the engines suddenly died (the difference is because of the fairly large range of heights that constitute "cruising altitude"). More modern planes can go even further from the same height. Planes designed to optimize that number can reach 360-480 miles if the engines fail (but obviously those planes carry less cargo).
