Space Forum / Shuttle / October 2007Follow That LOX Tank!
Jon Berndt referred to as fact: "... the explosive destruction of the LO2 tank and release of debris and propellants which destroyed the intertank, liberated the SRBs, and provided a nose outward impetus to both SRBs." That must have been one terrific "explosive destruction," Jon! At a velocity of about 2000 feet/second, it must have "provided" an unbelievable "veering" effect to those two stubby little tapered moment arms (the "toed-in" frustums) extending just above the thrust beam's forward-attach points. This is especially true when one considers that the two huge moment arms below that thrust beam were each about ten times longer than a wee frustum. Doesn't it bother you that Roger Balettie refers on his website to this allegedly devastating LOX-tank "blowout" (see "contrast-enhanced video" from Malabar) as simply the "ET forward flare?" Oh well, maybe it just bothers Roger -- since you're the one he credits with providing all that 'southern line-of-sight only' footage for his website. By the way, why is it that your own website does not show any optical footage of activity throughout the Challenger fireball, or any optics for the entry/exit dynamics of the 51-L boosters? JTM -- www.mission51l.com Hi John, Long time, not much typing from your end lately. Good to see you doing well, and haven't changed much. Speaking of 51-L, did you follow the mission prior to this one, STS-118. Barbara Morgan finally got to fly, and complete the last unfinished business from 51-L. It sure looked like she had a great trip, and NASA still owes her a day in space. They came home early, so hopefully she'll get to fly again. What spirit she has, watching the flight she could easily have died on, 51-L, and she still wanted to go into space. Dismissed and set home, she continued on, a thorn in NASA's side, until they finally made her an astronaut. Only astronauts can fly in space, of course. Then the Columbia Disaster, and another crew dies. The risks are great, and really evident, yet she still wants to fly. She finally gets her flight to Space, STS-118, after twenty years of persistence. True America Spirit. Didn't seem like she did much teaching from space, but it sure sounded like she did a superb job (and a lot of work) during the mission. Way to much mundane stuff, and not enough Teachering. And, as they say, any landing you walk away from is a good landing. That was the best part, seeing the Shuttle touchdown safely, a "good" landing. 51-L, mission finally complete, on STS-118. :-)  SignatureCraig Fink Courtesy E-Mail Welcome @ WeBeGood@GMail.Com > Speaking of 51-L, did you follow the mission prior to this one, STS-118. > Barbara Morgan finally got to fly, and complete the last unfinished > business from 51-L.

This was not a case of NASA owing Mrs. Morgan a chance to fly. Rather, she applied and was accepted as a real astronaut. She flew as a full fledged mission specialist as opposed to being a teacher in space. > Didn't seem like she did much teaching from space, but it sure sounded like > she did a superb job (and a lot of work) during the mission. Way to much > mundane stuff, and not enough Teachering. The teacher in space thing was more or less just a memorial to fulfill the mission and remember Christa McAuliffe. Her real job on the mission was to support the assembly of the space station. -john- Signature====================================================================== John A.

NASA isn't even willing to call her an Astronaut. I have a hard time singling out Christa McAuliffe. There was an entire crew of very highly skilled and educated people on that vehicle that basically trained their entire life to get a chance at a ride into space. Challenger was an accident that didn't have to happen, and all of these folks and their future potential were simply wasted. -john- Signature====================================================================== John A.

Also the Constellation series is built mainly upon improved shuttle components. So rather than wasted, I feel that they continue to contribute to Human space flight, and their sacrifice continues to reward us with knowledge. Admittedly their lives ended prematurely, but not without gain. As far as Christa McAuliffe is concerned, it is my opinion, which I know is shared by many, that she is, and always will be an Astronaut. Space flight participants pay money for their ride, Christa, Dick, Judy and the others paid with their lives. A title is simply a title. A rose, by any other name... Regards, Jim in Houston.

No we can't. Have you forgotten Columbia already? The damage to the wing was done during ascent. I'd hardly call that extremely safe considering the entire crew was lost on that mission. >> Can we say wasted when because of their sacrifice at least the ascent >> part of Shuttle flight is now extremely safe. > >No we can't.

I can't argue the point about the insulation. Although I was referring mainly to the SRB's. While it is true that the damage to Columbia was caused during ascent, the disaster occurred during landing. The chain of events was completely different. And no, I could never forget Columbia.
