Throttling up the engines above 100% typically indicates that the engines are being throttled up to 4% above original design specs for those engines. > ALso what is MAX-Q > MAX-Q is the area of maximum dynamic pressure exerted on the spacecraft, the engines are throttled down to 65% to keep the shuttle from breaking apart. Hope this clears up your confusion. Sorry about the lack of engineering detail, I design software not spacecraft. --------------------------------------------------------------------------- Alan Caldera System Engineer Computer Support Services Tandy Corporation alan@merch.TANDY.COM #include
