plenty of hot air but little to show, page-2

If you look at Para 20 Manning states "De Graf was reluctant to talk about GDY, why he left or why he was pursuing a different type of technology"
I think it entirely proper to be reluctant to discuss in detail the fortunes of one's previous employer or one's reasons for leaving.
In para 21 DG gives I believe entirely proper answers re GDY but more importantly he explains why he did not pursue HSA with GDY. What more does he need to do?

IMHO the article is a beat up.
