One more 747 video. A perfect example of why you plan and have calculations for your takeoffs and landings, because there is zero room to abort on a takeoff like this unless you realize very early on in the takeoff roll that there is an issue. You must be fully committed in your equipment and your calculations to pull this off, it’s NOT something you just “wing”; you can tell it’s quite humid or had just rained.  I estimate they had about 250+/- feet of runway left, by looking at the center line dashes in front of the nose-wheel at rotation.
