dr. griffin, would you care to comment? >> i would agree with general reaves with regard to certification of new capability. and i would say the idea we fly a large number of repeated copies of rockets is something that may look true from the outside but truthfully it is rare to go very long in a stream without upgrading or changing something about the rocket. you are in this continual process of evolution and certainly we don't do a non-value added test flight a whole separate test load because we go to an ro-10c. you would not want to spend that kind of money. when you field a new rocket you will do a couple test fights before you put a valuable pay load on it. there is an informed engineering and program management judgment that has to be applied to determine when you are willing to risk an upgrade without a test flight and when you need a test flight because the risk is so big you don't want to risk the pay load. >> and ms. mcfarland, some people have made unhelpful comments in the public that money from the rd-180 engi

dr. griffin went through. and my question for you dr. griffin is what is inappropriate now but it was appropriate then? was about program unsuccessful which now have commercial crew and commercial resupply. it seems like it's at least working. why is this different? >> will come and major difference i think it's in the amount of money involved. in the cots program at nasa taking us back to tenures, we allocated as we intended a very small amount of money across to providers, and the clear terms of the agreements were that there would be a very significant majority of corporate investment. that was our plan at that time. the program did work. we got two new launch vehicles out of the, domestic launch vehicles, the falcon nine and the orbital atk. i think it is a very different thing for the national security launch infrastructure to be told to purchase launched as a service, implying that there is an open market of providers from which the department can buy a launch on a marginal cost basis as if it were an airline ticket and all by the w

griffin. >> narrator: dr. bannish uses unorthodox methods to engage the inmates. today, he's giving them puzzles to solve. >> you see how enjoyable these guys are? i mean, they really are. they don't want to be grumpy they don't want to be upset. they want contact that's meaningful. (laughs) this is a good one. we'll see if you got that by monday. no conferring with each other, either! >> so you can't take it... >> i'm leaving in four-and-a- half months. they put me on the (bleep) bottom of the list. >> they didn't know. >> i'm about to freak out! >> they didn't come down and it was addressed, okay? >> narrator: two weeks have passed since adam was told he'd be able to take his ged. >> yes, they do. you're going to be getting your ged, okay? >> well, i want to (bleep) do some testing tomorrow. >> absolutely. >> or i'll snap. >> you know what? that's, that's a legitimate request, but you snapping isn't going to get it to you. give me a shot at trying to (bleep) help you out with the ged bit. >> yeah and that's been two weeks. this close! i'm (bleep) close! >> you b
