"BTW, this (just like the "twang" that happens between SSME ignition and liftoff) is something that is quite easily visible if you know about it and remember to look for it. "<br /><br />Never seen that before, but on the video you linked to its quite clear now <img src="/images/icons/laugh.gif" /><br />

With all the movement in the stack, I cannot help but be surprised there is no structural integrity problems created in the SRBs. What part of their structure works to absorb this sway? <div class="Discussion_UserSignature"> </div>

i dont care what anyone says. watching the stack flex like that at launch is just cool. seeing the nose of the ET shift or the vertical stab moving in such an exaggerated way really is interesting. and all that energy is restrained by what? 8 bolts at the base of the SRB skirts? (i know thrust to weight ratio isnt even close to 1:1, but still) <br /><br />edit: its cooler than the wingflex of a fighter jet in minimum radius turn. <div class="Discussion_UserSignature"> </div>
