is located in tucson. we visited the base to learn about its history and current mission. yearshas been over two since i got here. i've been flying the a-10 warthog. 1978 to 1979, we still fly in just that old. they have been built to go low and slow to stop tanks. they have been adapted to the current times. it is now adapted to in all day, all night, medium attitude type fighter. they were used in desert storm where tanks were widely seen. had 18dron here, we combat- assigned

aircraft are -- that are ready to go. they are built to be survivable. if you look at the jet, it is very high mounted with its engine. the engine is separated from the fuselage. if it catches on fire, it can earn and fall off. and fall off. the big wings create a lot of lift. maingeargear -- the does not go fully into the jet. the tires are still visible as we fly. land and breakl the -- brake the aircraft. there crafters a variety of bombs and missiles. a targeting pod, air to ground missiles, a full continent of weapons.

-- complement of weapons. the gun takes up the entire length of the aircraft. the nose year. if you look down the front of the jet, the nose gear is off the centerline of the jet so that the gun is perfectly in the front of the plane. i do not actually taxi with the nose gear because it is offset. it has a big, bubble canopy. it is all built for survivability, so the two hydraulic and electrical systems as far away get from each other as possible, so when we exit the hydraulic area one goes this way and the other goes this way. that way, if it takes a bullet, it does not hit both systems at once. bullet, itt hit by a

will not cause a fire, because there are no asked papers here to explode. all of my fuel cells can be separated, so that if i was heart of a wing and the fuel is coming out -- i can separate the system so i did not lose all my fuel. missing have come back entire engines or parts of their tail. they can take a beating. is the aircrew flight equipment room. it is like an nfl player locker room. we come in here after our flight brief, everyone is ready to go, and everyone knows what they are doing today. this is where we come to get dressed. my role is due train the new guys coming through for pilot training. fly in a tent, sometimes they come back for a -- an ar course -- an

-10, sometimes we have people that come back for a refresher course. some guys have already had three or four deployments. some guys have been flying for five or six years or more. they come back with lots of experience train the young guys. -- of experience to train the young guys. we have a wide birth of experience to train them with and make them even better than we were. this is our helmet mounted system. you have your eyepiece right here. it is the monocle. gets of information projected onto it. out the windowng at the ground, i can see exactly where the friendly czar, the targets are, other aircraft. --ith a friendly

friendlies are, the targets are, other aircraft. we can take a lot of systems that are tied onto here and they get rejected to exactly where we are looking on the ground. it is all tied into this cable that plugs into the jet, as well. it is offset through these fiber wires. really, the big thing about this newer technology for older aircraft has actually brought us back into the game to acquire and stick to targets efficiently and effectively. it makes us a very viable option and that are then we were as a a single usen fighter. with new technology that comes out, we get new and special ways of doing things that help us out

and make us more fast and efficient. >> right now, we are in the air operations center at davis-monthan air force base. our mission is to provide command and control for all the air force forces that operate in the southern command area of responsibility. anyone that is flying in aircraft south of mexico -- down across south america, we are going to watch them and make sure that the aircraft takeoff and land on time. that they operate safely. that they meet our mission objectives. these screens to be provided to the commander so they can have decision level information available to them. we have everything projected up there from the weather -- as you can imagine, in the area at the weather can be very turbulent down there. because you keep a constant watch on the weather in that area. we have other -- we try to keep a constant watch on the weather in the area. we have other tracking

capabilities to make sure we know who is flying and if they should be there or not. on the right side, we have the arrow aviation administration screen that shows the airplanes originating from the u.s. and going down to south america. we can monitor those aircraft, as well. it is a lot of information on the board so that the commander has that decision level in permission. we also help with the counter drug missions and combating terrorism, because, as you can imagine, criminal entities can -- drugs from south america and that can also odssibly mean terrorist go getting through. them -- economic, diplomatic, there are all different kinds of aspects of our area that we are concerned about. so, we offer a weeklong course

and other formal courses to make sure that people know how to operate the systems. this center is considered a weapon system come so we had certain qualifications that each position have to hold. there are tests they have to take and other requirements to maintain to make sure that they are experts in their field. >> the comment crude is made up of five squadrons. theintenance squadron -- group is made up of five squadrons. it fighter squadron, a maintenance squadron, and others. what we do on a consistent basis is we have the ability to interrupt medications or stop the enemy from receiving information. that is what the electronic combat groups mission is as a whole. we work with the coalition forces to get request for our capabilities to go up and

support different kinds of missions -- whether it be strike missions or special operations forces on the ground. we coordinate with planners. they request our capabilities when we get airborne. we talk with the required personnel we are supposed to check in with, and then we try to limit the enemy's ability to coordinate. we give our units a freedom of movement either on the air for the ground. there are four on the flight deck, a pilot, copilot, a navigator, an engineer. there is a maintenance deck with four lane which specialists. with a senior enlisted crew to electronic warfare officers in the back that are responsible for the mission portion. it can be tailored to the mission needs. assometimes can have as few eight or nine on board.

>> one thing that separates us from the difficult switch flying around is that on the back of our aircraft we had transmitter antennas. those provide us with jamming capabilities against targets in the low band range -- low band frequency range. looking up at the tail, you can hf antennas.ur transmitave some antennas located in the tail. the pod here looks somewhat familiar to older models -- two other models, but hours are high bandin regards transmit capabilities. remain thee systems same as previous models. on same engines do it see other models.

one difference is that we do not carry externals -- external fuel systems between the numbers three and four engine cells. these spear pod for by this with additional transmit capabilities against frequency targets. here, step around underneath the aircraft you can see a lot more of our antennas. othereparates us from models. a lot of the radios that we have are required on board to complete our mission downrange. -- some of these originate -- where the upgraded original models of the h one off the line.

1973 andhese were from 1964 models, and they have been giving us faithful service for the last 60 years. >> this weekend, we are featuring the history of tucson, arizona. you can learn more about tucson and other stops on our city towards -- cities tour on cspan.org/citiestour. you are watching c-span3. >> after came up with the idea, i decided to research information. this is part of the pieces that will be done for this competition. mental illness is such a multifaceted issue, in so i had to research to get a base knowledge of what i wanted to

talk about in this piece. obviously, it is so complicated that i cannot talk about it all in five or seven minutes. >> it is a very broad topic, so i thought it would be nice to have a focal point i can focus on. and researched the topic before i started shooting. coworkersth my dads and pharmacists. i would to the library to do a lot of research. >> a lot of internet research to find more facts and data in statistics about employment -- and statistics about employment of those with developmental disabilities. most of the information i got off the internet came from government found it websites. websites, and so that is how i knew most of the

information i was getting was legitimate to >> tell us, -- was legitimate. is the mostwhat important issue for the white house and congress to address in 2017. the competition is open to middle school and high school students with a cash prize of $100,000. students can work alone or in a group of three to create a five to seven minute that you -- bit of programming. prizes will in cash be shared among wanted hundred 50 students and 53 teachers. the grand prize of $5,000 will go to the student or team with the best entry. -- deadline is january 7 january 20, 2017. for more information, go to our website. studentcam.org. >> when philadelphia's museum of the american revolution opens in

april of 2017, 1 of their central artifacts will be george washington's headquarters tent which served as his sleeping quarters and office for most of the war. conservator, a textile engineer, and a museum vice president of collections will discuss the history of the tent. how it survived, and the techniques used to preserve and display the artifact. the american museum -- the museum of the american revolution posted be about. >> evening, everyone. i am scott -- good evening, everyone. i am scott stevenson. we are going to have a nice time talking about george washington's tent tonight. we also have an engineer that a ru
