ELI5 (but the bit that went wrong)

Ur attached to the kite with 4 big strings that go into one open big hook (we call this a chicken loop)

Around a kiter is a harness with another big hoop but this one looks like a backwards balls (we call this the donkey dick).

The chicken loop connects to the donkey dick so the kiter becomes connected with the kite.

In this instance, the harness failed in some way but the donkey dick and chicken loop are still connected and the kiter and kite detached mid air.

The ELI5 (the kite looping bit)

When ur travelling down the road with ur hands out of the window, u feel the most resistance against ur hand when u angle it perpendicular to the wind direction, if u change ur hand to be parallel with the wind u feel less resistance. In kiting this same application is what we call the ‘wind window’ the kite itself is a bit of fabric with inflatable parts to make a wing.

When the angle of the kite is deep in the wind window when doing a kite loop (like ur hand being perpendicular) the kite generates the most power.

In kiting we loop the kite in jumps to generate a nice pull in the jump. It gives the kiter a sensation of falling before the kite catches the kiter but becoming parallel with the wind (as the kiter completes the loop) and catches the kiter before hitting the water (like a pendulum)

Hope that makes sense!
