The CBKETT Theory applied to model aviation

  We now use a new psychological approach flying our models. In the past, our field was clear except for ONE TREE. As usual, the tree seemed to be endowed with magnetic qualities for model aircraft. No matter where the model was launched, eight out of 10 flights ended in the tree, hitting the tree or landing near it. So when it came time to test fly Quickie, we tried a place surrounded with trees. Why, you may ask? Well, I'l tell you ... We remembered the unknown CHARLIE BROWN KITE EATING THEORY. A close study of the CBKETT indicated that the tree did not necessarily attract the kite. Rather, the wood in the kite missed its "mommy" (being taken away at an early age) and mistook the tree as its long lost mother. Taking this approach one step further we theorized that the CBKETT might also apply to model aircraft. We further speculated that flying in an area surrounded by trees would so confuse the model that it would land before flying into the tree it thought might be its mother.

  We think we are onto something big because our model landed clear of the trees seven out of 10 flights ... an almost complete reversal of when models were flown in a field with only one tree. Perhaps one of you planning to work on your PHD might want to delve more completely into CBKETT and its relation to model aircraft and put it into more easily understandable terms. Here's your chance to make model aircraft history.
