One was to stretch the tanks and add a sixth main engine for a total of 9 million pounds of lift-off thrust. Another was to add solid, strap-on boosters. Yet another of the more ambitious proposals was to separate the main engines from the tanks and parachute them down for re-use. I actually knew one of the engineers who helped develop the F-1. He said that the only reason the engines were not re-useable was because they were at the bottom of the Atlantic. The engines were actually designed to be able to be used five to seven times. But, alas, so many good ideas never to be tried. Sigh.Paulhttp://www.blogger.com/profile/12654456307941311785noreply@blogger.com
