An idle 747 has a glide ratio of around 15:1, meaning they can cover ~150km from 35,000ft. My favourite example of this is the Gimli Glider - https://en.wikipedia.org/wiki/Gimli_Glider
Gimli is also my goto example on why metric
should be taught and used in daily life since an educated individual with metric background would likely have caught that calculation error (>1kg/l means a substance with higher density than water).
Thank you for sharing this amazing story!
The series Air Crash Investigation has an awesome episode on the Gimli Glider. A screencam is available on Youtube.
