Not speculating on the cause here, but of all the pilot's posting on this topic, how many have actually landed at Airventure, in particular, the 18 approach?

Having landed at Airventure more than a dozen times, it gives you a different perspective. All I've said is that the 18 approach requires a very close in tight left turn to final south of the 09/27 runway boundary. It would be a tough turn to make in a business jet if you are not used to maneuvering close to the ground.
