Thank you, Nick. The absence of specificity regarding second order conditions for stability is not important, and the very absence of data attests to the purity of thought. See, for example:

Luckett, D.G. (1971) The Inverted Tetrahexahedron: A Personal Account of the Discovery of the Structure of the ICBM. The Journal of Political Economy 79(4): 933-937.  (Jul.-Aug., 1971)
