Robert, schools today use modern math, and what amazes me is how you can make an equation without knowing all the facts. In My original letter that some thought was rambling I brought to you the facts as they stand and accurate. Using names, dates and times. I find none of that in your equation of time. Don't assume, go back and re calculate and find out the missing numbers. Please, it was not traffic safety. It was aircraft safety. It has to do with manufacturing, assembling and aircraft flight safety. Remember this. The next time you strap an aircraft to your donkey, you had better hope me and my associates have done their homework. It was a good try and I am pleased with your response.
