I was just reading Clavius' arguments against Sibrel (http://www.clavius.org/bibsibrel.html) and I have a question...
Here I quote from that page:
"The lunar module was never tested on earth. It couldn't have been. Its engine was too weak to lift the spacecraft against earth gravity, and the lunar module's structure can barely hold up its own weight on earth."
Ok, fine. But if the LM's structure could barely hold up its own weight, then how did it support itself during the Saturn V launch? Did it get extra support from being stowed within the SIVB?
(I'm not proposing this as a conspiracy--far from it. I'm just curious...)
