I work with a guy who goes out to ADP a couple of times each year. He always comes back with some horror stories, but im not sure if they are down to him or the aircraft. He does always wonder if the u/c will come down when he pulls the handle. And honest to God, he rented a twin and they told him he could have it cheap if he didnt put the wheels up after take off, cos they werent sure if they would come back down! Like i say, it worries me, but he keeps going back for more, so it cant be that bad. Can it?
