Pat I wonder what Bar Sibrel's doing right about now.... If real photos from the surface didn't convince him, why would real photos from orbit convince him? He's just going to claim they're faked too. Yep. I was just wondering ;-) |

Pat Note the black 'hole' in the top of the Descent Stage: http://www.nasa.gov/images/content/5..._AP12_area.jpg (zoom in). They look like they might have come close to a 'brew-up'. Not sure what you mean by that; the hole was always there and ascent stage ignition was always intended to be "fire-in-the-hole". There was a thermal and micrometiorite sheild - http://jeffreyellis.org/tlmp/files/facts/lm_descent.gif. I think it was also intended to prevent the Ascent Stage thrust from getting into all the tanks etc on the Descent Stage - no BOOM. Propellant was vented, but then there was the pressurising gas and any residual oxygen in storage. I knew about the shield but thought it only covered the tanks, not the descent engine compartment in the center. The cutaway drawing you linked doesn't make that clear either. There aren't many pictures of the descent stage from above, but this one shows an open hole http://www.apollomissionphotos.com/apollo12/108ksc69p220.jpg |

It would be fun to know where the boulder came from. Pat Shhh... the monolith is hidden inside it. ;-) |

I've always thought that one of the public relations failures of Apollo was they never went any place interesting enough to compete with the Bonstell paintings that many of us were familiar with. |
