Just for accuracy, a few comments in response to Chris Scott's post #270):

Regarding Chris' stall condition (1), I don't think it is such a 'rarity' even for conventional airplanes.
Regarding Chris' (2) I am somewhat sceptical but can't comment because I wasn't involved in BCAR certifications in those days. However, strictly speaking the so called g-break speed is close to but not equal to the 1-g stall speed, and both are not obtained at 1-g in the stall maneuver. The 1-g stall speed is the lowest speed at which wing lift alone can support the weight of the airplane in 1-g flight. It is defined by the point in the stall maneuver at which the lift coefficient cL is at a maximum. At that point the normal acceleration is usually not equal to 1, and the reference stall speed is then calculated as Vs1g = V(cLmax) / √(nz)
Regarding Chris' (3) I would observe that, although the minimum speed in the stall maneuver is usually at less than 1 g, it is not obtained at 0.94 g, nor at √0.94 g.
