As I noted in an earlier message to the group, the info I have on the models
is in hard copy. Thankfully, Neil has the capability to convert them to an
electronic format and has agreed to do so. I have mailed them to him. He will
put them in the pile of info going onto our home page and let us all know
when they get there. A good reference for the SHEL model is Frank Hawkins
book, "Human Factors in Flight", second edition, edited by Harry W. Orlady,
1993 from Ashgate Publishing Company.
Sorry for the delay gang, but the response was substantially more than I
bargained for.
