How many times did you go up?We often had to hit a very specific velocity at Main Engine Cut Off (MECO). They were in the range of 25,950 fps - almost 5 mi/sec. And we hit them routinely, within a few fps. A couple of hundred fps over and you weren't in the correct orbit (overspeed). A couple of hundred under - you were coming home unless you performed some extra burns.
Ian, I was at the US Army Ordnance Guided Missile School at Redstone Arsenal in Huntsville, Alabama in the spring of 1961. One Saturn rocket engine was fired on a test stand there and it literally created a small earthquake. The ground shook and its noise was heard for miles; it was impressive.How many times did you go up?
we visited Kennedy Space centre last year and The boosters were impressive, but not as serious as the Saturn5 ones.
