You must have been on one of the other forums and read about the Landmark, had there been anything to explain what happened??.........I haven't really followed exactly what happened, but I really wonder if the owner hit the Auto Retract function by mistake. The only other way I could see that happening with be a burst hose on the landing gear and not even sure that would cause the issue.
