Thank you Bill.
correction :
Quote of "60 degrees" should be replaced by "over 30 degrees", basically 30 to 45 degrees depending on some details.
I had to do some quite calculations and took the wrong angle when writing my initial posting. Any wing will stall at 60 degrees angle of attack (even delta wings), so I should have spotted that immediately.
Sorry,
Wouter
