I use U.S. Code 107 (The Fair Use Doctrine) to help protect me from copyright infringement since I do what I do for educational purposes only, without regard to any monetary goal. The law can be read at the web link as follows:

I never leave anyone un-credited for their work, and sincerely apologize for leaving anyone out, if that ever happens.

The fact is that my work makes other people's work look fantastic, yet I only fix these things because it is neceserry. If the aircraft designers would take about 20 hours to test-fly their creations, there would be no need for me.

Any problems or questions should be directed to me:
