this is a video of why a good preflight is a must.
(the right side cable supposedly disconnected on takeoff)

Just imagine if that were to happen at Kagel!!!

why good preflights are a must........
Are you sure?
Not that a good pre-flight isn't a good thing.
But this glider loaded up prior to the wire snapping or coming loose. Hard to tell what the real cause was but clearly the cable comes off.
Along with a good pre-flight a good annual or better yet semi-annual inspection would be a good thing too.

I like what the Wills Wing manuals for their current hang gliders tell you to do for part of a pre-flight check; The manuals state that you should:
"while pushing up on the leading edge between the nose and the crossbar junction, step on the bottom side wire with about 75 lbs. of force. This is a rough field test of the structural security of the side wire loop, the control bar, the kingpost, and the crossbar, and will likely reveal a major structural defect that could cause an in-flight failure in normal operation."
(I believe that the T2 manual states to use 50 lbs of force and leaves out the kingpost in the description of the stuctures being tested since it doesn't have a kingpost.)
Every time that I do my preflight, I always do that "step on the bottom side wire" test on the right and left side wires. I sure hope that most people do this test when preflighting their glider because it's a quick test and makes a lot of sense to me.
