Dan, e-mail, 12.09.2014 18:13 Fantastic! I've been into this tip jet tech for over a year with the idea that this might be a way to design a low cost, safe, kit ultra light helicopter, that could be sold through Amazon for less then twenty grand. Thanks for this post! Check out the Monte Copter for a similar history.

It was gradually disassembled over the years as he moved with various parts becoming part of a mock up he was doing for a light sport aircraft. After his death the mock up was scrapped. I now have the N number on the section of the right side aluminum as shown above.

Steve Cole, e-mail, 15.03.2012 15:52 My Grandfather, Willis Cole Jr. worked for McDonnell. Somehow he acquired most of Big Henry when the project was cancelled. There are pictures of it sitting in the family driveway. Up until a few years ago, the landing gear, instrument panel and a piece of the fuselage (with the N12M number) were still floating around his garage. Willis Cole Jr. passed away 3-16-2012.
