my dad used to work for gummans in the '60s. he was an engineer on the lem. do you have artifacts from the lem and moon shots there, and also semper general dailey. >> it's great to have all the marines on the line tonight. i'm not sure i understand, do we have additional artifacts from the lem? that's the question? >> exactly. >> of course the ones that went to the moon are still there. this was -- because the program was cut short, that was the reason why we have this equipment available to us. but this one we have on display is configured identically to the one that went with the apollo 11. we have other artifacts associated with lems but everything we have on this is installed -- in fact, this is the most complete display that we've ever had on this particular artifact of it's been on display here for 40 years. but now an individual who was actually involved with the original configuration of the lem for apollo 1 is came in and did the work on this. so we are very pleased with the exhibit and it is authenticity. >> can you can look ahead 40 years from ton
