-- >> at of tuesday's debate, we will take a look back at the candidates using the c-span video library. this storyeen before. turned on the television and seen the bad news of a famine or a weather emergency. there was something in the store yesterday it was different. it was you. your spirit of even in a dark day of optimism, community, and hope. >> the presidency is the most visible thread that crawls through the american government. more often than not for good or ill it sets the tone for the other branches and spurs the expectations of the people. vast and consequential, requiring from the out set the definition of impossible fulfillment without humility and insistent attention to purposes as set forward in the

constitution. >> a look at tim kaine and mike pence, monday night at 8 p.m. eastern. c-span.org andn listen on the c-span radio at. -- app. is visiting pueblo, colorado this weekend. coming up next we will visit the air museum and hear about the city's contribution to world war ii. >> we are at the pueblo weisbrod aircraft museum in pueblo, colorado. this is located at what was the site of the world war ii pueblo airbase. at the opening of world war ii, there was a tremendous need for training americans. so, even prior to the bombing of

pearl harbor, pueblo had been looked at it identified as a potential location for a training facility. it was late in 1941 that the ordinance dave -- tempo was located to the east. -- depot is located to the east. initially coming in and out of the base it was transport type aircraft's, bringing in personnel. later, though, we had b-17 flying fortresses coming through here. so, we would see these flying fortresses up over the city. pretty soon we heard about the development down in ordway. we had bombing ranges set up so that the flights that went out of pueblo were not only familiar flights for the new cruise that

were arriving to fly the b-17's -- crews arriving to learn how to fly the b-17's. the flights would originate in pueblo. many of the flights would go down to the gulf of mexico for practice bombing missions. other flights, i heard airmen talking about practice bombing from the golden gate bridge. they would fly clear to california and rectus bomb runs. -- and practice bomb runs. it was navigation bombing, all the facets of warfare were trained here at the base.

locally, we had bombing ranges. they had navigation flights learning how to do that properly. the b-17 was the first aircraft i saw flying out of pueblo. then, it shifted to the b-24 liberator. principal of the period of -- for the old of the period of time the airbase was in operation, it was the liberator that was the principal aircraft that was used in training. our school was only two miles from the fence. we were able to see these aircraft's taking off at all times during the day. even into the night. towards the end of the war, we

were a little surprised when the b 24's started leaving and the b-29's started flying out of the pueblo army airbase. what we later learned was that the intention was we were training trainers here at the pueblo army air base with the expectation that if the war with japan was to be extended, we would have to have more b-29 training facilities throughout the united states. the groups the trained here in way below -- pueblo were intended to be training groups to set up other training programs around the world, the country. with the end of the war, that all came suddenly to an end. the planes rapidly disappeared from pueblo. >> the aircraft behind me is a

fortress. the british originally thought they were not going to be successful in their fight against the germans during world war ii. the aircraft was designed for a flight to europe, conduct a bombing mission, and return to the united states. it was named the euro bomber. thank god, as it turned out, the brits were successful. this aircraft was already on the drawing board and was capable of missions flying great distances required over the pacific. they were based primarily out of china, but they could only reach the southern parts of the home islands of japan. as we move forward with the

invasion operations throughout the islands in the pacific, when we reached the marianas, that's when the b-29's were staged heavily, in those islands. this aircraft never quite made it to the war. it was very heavily utilized after the war as a reconnaissance aircraft. once we got it, we had to put it back together again. one of the things you may notice, these rivets are raised. this tells us that this was an after-market modification, if you will. these are the original factory rivets. the difference is these are flushed. this allows the wind to go smoothly over the aerodynamic body of the airplane. these are raised, because we don't have the capability of

flush riveting. the air force found had they left these rivets up, it would've slowed the aircraft down by 40 miles per hour. these were never painted. if you painted this airplane, you just added 4000 pounds of weight. right now, we are in the nose section of the b-29 "peachy." this airplane has a number of different stations. all the way in the nose is the bombardier. he has the bomb site, and his actual work in a 16 or 18 our mission lasted five or 10 minutes. when you move back a little bit, to the left, is the pilot position. this is the seat where the pilot would've been sitting during his mission in august of 1945.

to his right is his copilot. in the event the aircraft commander or pilot needed some relief, the copilot would take over. he was also very competent and capable. directly behind the copilot is the flight engineer. this is one of the most important positions on this airplane. the flight engineer monitored the performance of the engines and the systems within the airplane. this was the one job that never got any rest. he was constantly on duty. since he was the flight engineer, he was also crew chief, which meant any work or post mission repairs it had to be done were also his responsibility. our dose of reading says he probably got sleep maybe eight

hours out of every 48 hours during a mission push. i'm sitting at the radio operator's position. the radio operator communicated for both his airplane and possibly a whole section of aircraft. he was also responsible for assisting the navigator, whose position is directly across the airplane, on where they were in 80 given period of time. what we have here is a 1942 indian motorcycle. as you can see, this was configured to be a security vehicle. should the operator of this vehicle -- when he is doing his normal perimeter check, driving this motorcycle around the airfield -- should some have attempted to come in, he has a thompson machine gun with which he would dissuade the person from entering.

he had extra ammunition. this vehicle is on loan to us from a gentleman who has an automotive private collection in trinidad, which is south of us here. the vehicle does operate. and we get a lot of guests who desperately want this motorcycle. but it is hours, -- ours, since this actually served here at the air force base during the war years. the display cases behind me are artifacts brought home from conflicts past by our fighting forces. back then, you could bring home war trophies. it's pretty much for bid and nowadays -- for bid and -- forbidden nowadays. you can't bring things back with you. back then, you could.

the biggest thing that people notice is the large nazi banner that is hanging from the wall. this banner was taken by one of the infantry divisions when they were clearing a germantown. they were made by the nazis by the tens of thousands. they were draped everywhere throughout germany during the war. one of the commanders of the infantry division said, tear it down. a g.i. tore it down and folded up and put it in his backpack and brought it home. somehow, it made it here. we've had it cleaned once. the folks at the clean establishment said, never bring this back again. not because they had problems with it. it was so inexpensively made and it was so fragile, they said the next time you run through the washer, we may tear it up. we don't want to do that. she will be the -- she will be displayed as she is right now. i think the pueblo army air base reflected a community support.

the level was so great. part of it, i think, is because of the diversity of this community. we had italians, we had slovenians, we had slovakian's, hispanics, we had whites, we had germans, we had everything. pueblo was a real melting pot. but the people were well below -- were puebloans. they were americans. i think we had a pride in the city. i think we put up against any community. no community could've worked harder or cared more for the betterment of america and this united states. >> this weekend we're featuring
