Returning to Donald's original question, repeated at the end of this message.

I have been interested in the thread that started this.   Lots of good
comments have been posted.  No one has directly address Donald's
question vis a vis the F-22.

The F-22 software is clearly a problem.   There are probably programmers
out there who read these forums and have direct involvment with
this project.   It would be interesting to hear from one or more of
them.
