I do remember the GT stage now that you mention it. From Gemini 5, and it survived for the most part.<br /><br />I don't know how they recovered it and why it was so easy.<br /><br />So it is possible, then, that some rocket stages are out there intact. But Curt Newport (LB7), though I'm sure he would if they had the funds, said as I recall that it is unlikely any Saturn V stage is out there intact.<br /><br />I'm not sure how far up the Titan 2 stage was released vs Saturn V.<br /><br />In 2003 they did an experiment trying to recover the boosters off an Atlas 5. All they recovered was a nosecone. On nearly all the Atlas 2AS launches in fact, the boosters were so fragile that they broke into pieces when separating from the vehicle due to aerodynamic forces. And a few years back, the nosecone of an Ariane 5 SRB floated to the Gulf Coast all the way from the Atlantic.<br /><br />So things survive, but the question is how large, how high is the fall, and at what speed.<br /><br />There are two spent Shuttle SRBs on the ocean floor as well. <div class="Discussion_UserSignature"> <p>-Ben</p> </div>
