Here's a link for you, XXX: Holland with all his knowledge and experience may have just gotten a little complacent about how well he really understood and applied the basics of how and when an aerofoil stalls. Sound familiar? I sense a similar attitude in some of the postings here, and hell I certainly know very little compared to some of the posters here in some areas, but does that mean I shouldn't speak up and try to further my and everyone else's knowledge by having a spirited discussion? You tell me!
