Default RE: Making a Good Landing

Now that many of us are thinking about the landing problem I would like to share an interesting experience. About 10 years ago I decided to design and build a Flying Lawnmower. Others had already done that and there were a few balsa kits available. I had already scratched off building a balsa kit after seeing a balsa Flying Lawnmower making a poor landing. It was totaled. After I discovered building planes from Coroplast corrugated plastic material, that others had pioneered, known as SPADS, I realized that a Flying Lawnmower using Coroplast was very possible. When I was doing the maiden flight, during the first landing, I got that sickening feeling just before touchdown, that the plane was going to be totaled. It appeared to be falling terrible fast. I merely held on and the landing ended up being as smooth as silk. I did a few more landings and had that dreaded feeling one or two more times, but soon it disappeared. Over the next few days I kept wondering why I had that feeling of doom during the landing. On my next day of flying I made a few flights but the dreaded doom did not appear again during the landing. Then I talked my flying buddy into taking it up. He discovered that same dreaded doom during the first few landings also. After a lot of thought I decided that the dreaded doom was some type of optical illusion resulting from the fact that the Flying Lawnmower does not have wings, it is a lifting body, and that this missing item was causing our brain to decide there was something wrong. Apparently during the landing we receive information from the AOA of the wings to judge the landing.
