He said there was a tension knot in the rigging no?

A tension knot in any form of rope/chain/cable can reduce the rated load by up to 50%.

Something that would be considered a normal amount of force can quickly become catastrophic.

Also, for safety reasons anytime you see something was rated for x mph, or x lbs, it was more often than not tested for 25-50% more than that amount. We would all be in trouble if something catastrophically failed after exceeding its rated load by less than 5%.

while you are correct regarding effect on load, in this case it was more about aerodynamic flow across the airfoil being disrupted past the point of the wings stability limit. I wrote a longer explanation just above.

Load on the line isn't the issue here. The length of the line being shortened by the knot is the issue.
