Hendecagon of a regular hendecagon is still impossible even with the usage of an angle trisector. It can, however, be constructed via neusis construction and also via two-fold origami. Close approximations to the regular hendecagon can be constructed, however. For instance, the ancient Greek mathematicians approximated the side length of a hendecagon inscribed in a unit circle as being 14/25 units long. The following construction description is given by T. Drummond from 1800: On a unit circle: The "regular hendecagon" has Dih symmetry, order 22. Since 11 is a prime number there is one subgroup with dihedral symmetry: Dih, and 2
John H. Sides Burke summoned Sides, Freitag, and other Navy missile experts to his office for a briefing on the FBM research studies. By the end of the meeting, Burke had reversed Carney's veto and committed the Navy to an all-out FBM development program, directing Sides and Freitag to work out the operational details. Sides handled the Navy's side of negotiations over how exactly to implement the Killian Committee's recommendations, which called for the Navy to develop a ship-launched FBM similar to the Army's Jupiter IRBM. On September 13, 1955, President Dwight D. Eisenhower accepted the Killian Committee recommendations and directed the Navy
