This morning I was making the short flight over to the M20Doc's shop for some minor maintenance. When I arrived, I was still sitting in the airplane organizing my things when Clarence walked out and I heard him gasp - my heart almost stopped, I looked up and saw what he was looking at, a good chunk missing from my prop. On departure my prop must have picked up a pebble, I've seen many small dings in props before but nothing like this.
