the distance would depend on the breaking strain of the rope. Once the length of rope down the hole equals the weight of the breaking strain, then it would ....er...break.
OK?
Or were you referring to the aeroplane?
That?s a stupid answer!
The question was how far could you (me) lower a rope down a hole or well or something?
Fact is, I couldn?t hold a length of rope that was soooo long that it broke under it on weight.
I think my answer was best.
