I had no problem with old aircraft until the crappy flight school tried to blame me and other students for their maintenance problems. One of their airplanes, the mechanic told me the engine was so corroded the airplane should not have been flying. I ended up hating the flight school where I did my PPL. They only seemed to care about how much money they could squeeze out of me. The last straw was when I finally realized they dragged everything out to get as much money as possible. I don't like people lying to my face and screwing me over for money. I still have a passion for flying, but I go to another airport now.
