The quite overweight, less than ideally skilled pilot who used to keep his Cherokee 140 at the aerodrome I used to keep my plane, ran off the end if the runway, at just flying speed, and managed to climb away unsafely. He'd run it through the corn cobs before managing to climb out of it (the prop swath cut was quite something when I walked to the end of the runway the next day!). The leading edges of the Cherokee were fairly well dent in by the corn cobs. He flew it for repair (yeah, you read right). A few weeks later, he returned with it, 'same 3/10 paint, and a shiny new STOL kit cuff covering most of the leading edge damage! He and I did not agree on much....
