The "[ame="http://www.orbithangar.com/searchid.php?ID=3881"]CSM scenario pack[/ame]" addon doesn't have any actual CSM-based scenarios in it, but the screenshot on the OrbitHangar page gave me an idea. I used Universal Cargo Deck to put the Apollo CSM/LM stack inside the Space Shuttle cargo bay, and it fits almost perfectly . This should be too heavy to reach orbit (the CSM/LM's total mass is 45098kg, but wikipedia says the shuttle's LEO cargo capacity is only 24400kg) but for some reason I can put it into orbit easily, even though UCD is supposed to add the mass of the payload to the shuttle's mass (and it does do that).
