The information in this is very good, but it was difficult to read because the text all ran together.  

Dang it!  Megan beat me to my question.

You said that Hughes would perform any stunt that one of his pilots to do so he could find out what they meant.  Did they film him doing that and use those cuts in the film?  Do you know if any of his pilot's changed their mind after Hughes flew the stunt?
