<blockquote><font class="small">In reply to:</font><hr /><p>That to me is the problem. The fact that we're not going to have a third tanking test is a product of this problem, although as you've (and many of my co-workers have) pointed out, it'll become the third tanking test anyway if we do have another prepress anomaly... don't know if you guys were aware of this or not, but they've tightened LCC ET-04 a bit - for STS-114 ONLY, the max prepress cycle count will be 11 instead of 13. So, I'm happy about that - although I will be biting my nails when ET-120 does get to fly (STS-121) in case the problem was NOT with the diffuser.<p><hr /></p></p></blockquote><br /><br />robot, I do have great sympathy for your viewpoint with respect to complacency creeping back into the program, with potentially catastrophic results. However it does appear to me that all the bases have been covered with this issue, in as much as you can be certain of anything when operating Shuttle.<br /><br />As has already been pointed out, a continuation of the prepress anomaly with Discovery's new ET will result in a launch scrub. Vehicle and crew safe. Additionally, the changeout of the diffuser on ET-120 is believed to be the correct remedy for the anomaly it exhibited, if obviously not a unanimous view. Should the anomaly represent with Atlantis there will be vindication for your view. Though, most importantly, a launch scrub will result with vehicle and crew again safe.<br /><br />I'm sure your discenting viewpoint has been noted in coming up with current plan moving forward, and it seems unlikely to me that special attention won't be given to how both tanks prepress over and above the conditions put in place? Especially bearing in mind that there has been discenting viewpoints expressed during the discussions of this anomaly.<br /><br />Ultimately safety is the primary concern, for both crew and vehicle, and I can't see how that hasn't been adequately addressed. <div class="Discussion_UserSignature"> <p><em><font size="2" color="#ff0000">Who is this superhero?
