The Shuttle launch & reentry were flown by computer because they required precision far beyond human capabilities.. NASA disallowed the much easier computer landing so there could be no unmanned shuttle flights, & so deliberately unnecessarily risked human lives to haul groceries up & waste back at 10 times the cost of commercial boosters. NASA’s shuttle was the most dangerous, unaffordable & unreliable space vehicle in history.

Its poor lift/drag ratio is partly due to its low aspect ratio wing. When within approximately 1/2 or 1/4 wing-span of the ground, the surface limits downwash angle and therefore erases much of the lift-induced drag. In short: ground effect improves efficiency.

@7:30 I was ten-year-old kid when my family and I showed up at Edwards Air Base in 1977 to witness the first-ever flight of Space Shuttler. So many people showed up to watch the event, and it took lot of us hours to drive out of the base to the highway. That is one of few things in my life that I would not forget. The other was watching Concorde taking off at DFW airport in 1979 at full throttle with afterburners (DFW was only one that allowed the full throttle due to sparse developments surrounding DFW).

[@forgonenapster8888]

Hi Scott--Very Well Done! I got into the program about 1 year after these tests were completed. I'd like to make a note here if I may-- With the tail cone on, glide time was 5 1/2 minutes, with the tail cone off it was 2 1/2 minutes. Quite a change!

[@pommiebears]

You read as important. You got into the program? My son has just joined the airforce, and he isn’t even flying. He’s an armament technician. I’m worried sick about him lol. I can’t imagine the things you have seen and experienced. Takes guts to do this, and I admire it immensely. Just a question, isn’t the cone supposed to facilitate, assist, in aerodynamics? Yet, it was 3 minutes quicker without the cone.

[@dandeprop]

@@pommiebears Hi Pommie: Please understand, I didn't fly the vehicle. Thank you for the kind words, but nothing I did took any real 'guts'. The worst that can happen to a Test Conductor or Flight Director is that he/she might fall out of their chair. Regarding the tail cone--in the beginning of this program there was great uncertainty as to what flow over the base area of the vehicle would do. The presence of the engine bells greatly complicated this situation. And in fact one of the biggest reasons for the tail cone was due to uncertainty as to the 'dynamic environment' that the Orbiter base flow would induce to the 747 carrier aircraft. Since the flow over the Orbiter base also tended to flow over the 747's tail, there was FUD (that's space talk for 'Fear, Uncertainty, and Doubt'...) as to how much this would influence the 747's yaw stability. After the 1st captive flight without the tail cone, the 747 crew was quoted as saying something to the effect of 'We don't want to do anything like that again!' I think there were structural modifications to the 747, as well as modifications to its flight control system after that. Wow: this stuff was a long time ago! Thank you very much.

[@jcoghill2]

I worked on the shuttle carriers. If memory is correct they had a turbulence problem with the horizontal stabilizer that caused a severe oscillation that left the 747 barely controllable. The fix was to put the vertical fins at the tips of the horizontal stabilizer. Took the oscillations right out. The shuttle carriers flew on Uncle Sams dime so they got JP-4 not JET-A. The first day of work the plane pulled in with this sweet smell and so unlike the airline aircraft I was used to. I love the smell of JP-4 in the morning.

[@fastfiddler1625]

I can only imagine what these early fly by wire systems felt like. After thousands of hours in traditional planes, my first A320 sim lesson was rough; I was constantly chasing the plane. My second flight was perfect after I really took home that "less is more" when flying those. In a normal plane, you're used to constantly working to keep the airplane where you want it, especially in slower flight; you learn to feel the plane and almost react before the plane even starts rolling left because of some turbulence. In FBW, and particularly the airbus, it's quite the opposite. You use the controls to tell the airplane where you want it to go. It's super easy to create PIO (pilot induced oscillation) if you're trying to fly it like a regular plane. This is partially because there's a bit of a lag between you and the flight controls. So what you perceive as the plane getting pushed in a left roll, the airplane already knows and is doing something and then it sees your input to roll right and it thinks, ok he wants to go right, so suddenly you're over to the right instead of level. Granted I am NOT a test pilot and I'm sure these guys knew quite well what to expect. But in a traditional plane that might have some aerodynamic quirk, you kind of learn the feel quickly and go, ok, that's what I'm dealing with. Where in FBW, you're left with the classic question: what is it doing now? Or why is it doing that?

[@0MoTheG]

That is why the suggestion was to let go of the stick. The control system does not have enough authority to meet any input. Humans tend to update twice per second in a "dead beat" fashion leading to a 1 Hz oscillation. An impatient human will try to generate a faster response by larger input.

[@JamesJoseph-u1y]

Flying a FBW flight control airplane is more like “flying” a spacecraft. Very different than a conventional jet as much of the aerodynamic feel and feedback you get from a conventional flight control system is absent.

[@LuLeBe]

Funny that you found it so difficult. Did you have a type rating on another aircraft before? When I was in a 320 sim, it felt as stable as it gets. I can’t follow your PIO observations at all. I do see what you mean by it feeling a bit sluggish, but then again you can yank it full nose-up (or rather max G) with very little force.

[@davidpearson5574]

I worked the early days of the Space Shuttle program.....as I remember, Enterprise was intended fly to orbit, but during the time enterprise was being built it was discovered that the wings/tail were not strong enough to fly through the maximum dynamic pressure region of ascent flight. The Wings and Tail could not be made strong enough without costing a lot of payload to orbit capability, so Day of launch wind biasing was baselined. This required balloons to be launch several times prior to launch. The balloon data was sent to Rockwell in Downey, CA to run a flight simulation, and then structural loads to be estimated. These results was then briefed during the launch Go/No go decision meeting. I was also in the Downey control room during this last flight of Enterprise....I though he was going to stall....was not a pretty landing!

The rest were the natural rusty orange color, which woodpeckers loved (As an aside, there was a guy on the launch tower whose job was, if he saw a woodpecker, to blast an air horn to scare the bird away.). Not painting the ET shaved between 600 to 800 lbs of useless weight. The extra weight wasn't that great in comparison to the total weight, but given that, to put 1 lbs. of payload in space, it took around 7 lbs. of fuel.

[@johnshields9110]

The Shuttle program held a big personal interest for me as a young teen, and throughout its life. My BIL worked on improvements to the C-130 tail, which lead to the design team for the main booster guide fins on the Saturn V. I had a brother in Air Force flight flight training, and I later attend college as an AFROTC Pilot rated cadet. Historically, I followed all the designs on WWII and Korean War aircraft, as I was an advanced math student from early age (college degree was in Mathematics), so I followed the Shuttle designs with interest. Few people recall that the NASA engineers used the earliest 'lift body' data from the wingless M2F2 aircraft, which had been propelled by being hauled down a runway by big V8 hotrodded Chrysler! I think the Century series Fighters provided gross examples of problems using ailerons vs rudders on how to turn an aircraft for final approach (the Shuttle wouldn't survive an episode of the deadly "saber dance"). When the Vietnam War ended, I signed out of the flight program; I had gotten too tall for fighters cockpits, but lived on through flight with the mathematics.

I’ve been looking for years for any picture of the shuttle simulator. Finally you showed a few seconds of it. I remember in Southern California they had two stationary shuttle flight decks simulators nose to nose. One of them would be hooked up to a camera on a gantry in the room. I remembered the near as big as a football field. I believe on the floor was a model of Florida. Edwards Air Force Base would’ve been on the wall. And the ceiling was the alternate landing site in Puerto Rico. They would actually fly a camera in the room on gantries. So detailed you could actually crash through building models in in the Florida model. All I n the days before electronic flight simulators. I believe the 4 shuttle computers were only 16k of Memory. Three working to check each other’s work and a fourth one to be brought online if one was found faulty. I was starting to think I was crazy because I’ve never been able to find a picture of the mechanical simulator. They also had a Shuttle arm simulator

[@willmorici5765]

I remember several times with Enterprise: 1. Stacking Enterprise with inert SRBs and ET in the VAB and doing rollout tests to Pad 39A. 2. Stacking Enterprise out at VAFB and rolling it on the road (that was a nightmare as the road was tight and had some interesting turns. 3. Testing the leading edge panels following the Columbia accident (that was a sad time!)

[@rpsmith]

I use to work at J.S.C. on the Space Shuttle Simulators in the early 80s and we often tried to land the Shuttle but never once came close! It was a brick with wings and you had to anticipate your control movements way before your natural instincts. As you might expect, the Astronauts made it look easy. :o)

@@SeanBZA and the Right Control systems even a brick can fly ;)

[@Yaivenov]

@@SeanBZA Israeli F-15 lost a wing in a midair. Solution was to accelerate to 300+ kts and have body + deflective lift take over for the missing wing. At that point the remaining wing was just an aerodynamic fuel can and the plane was flying on thrust, body lift, and the independent control tail planes and rudders. And the topper: he successfully landed it crossing the threshold at 300kts. For truly the most extreme case of a flying engine with a few control fins attached, check out the F-104.

This brings back many memories. I was in the AF from '78- '82, stationed at Norton AFB as part of the 1835th EIS. Arriving TDY at Edwards in Summer '79 I got to witness many, many test flights of the 747/Shuttle coming on and off runway. I used to marvel at the skill it took to do touch and goes there. My groups job was to install commo, metro, video and data cabling across Edwards for the glide tests onto Rogers Dry Lake. We spent months out there working on that. It was a turning point of my life actually. I was part of a mission, working with a bunch of great people with a time line that had to be met. We pulled this off a few months ahead of schedule. Some of the work we did was right along the active runways. I remember watching the transport combo taking off etc maybe 300 feet away from where we were working. Also slews of the coolest planes I've ever seen. NASA stuff, old F-102's, 106's, A-7's, modified B-52's. It was just a real source of excitment for a young country boy. Great video as always!!

A few years ago I got to see Shuttle Enterprise at the Intrepid Air and Space Museum and its the only shuttle ive seen in person and it was amazing to see.

[@quaidbergo]

Very cool tidbit about the longer attachment pylons for the test flights to achieve the required AOA. I never knew that.

[@hoghogwild]

Yup, the ferry flights used the shorter front attach struts to save fuel as it holds the Orbiter Vehicle at 3º AOA, while flight/glide test used longer from struts to maintain a 6ºAOA. Even so, the 5,500 N mile no payload range still decreases down to 1000 nautical miles with an orbiter on the SCAs back..

[@awuma]

I noticed it immediately in the video. The "Enterprise" really did poke up higher. Never noticed it before, though.

[@hoghogwild]

@@awuma Yes, but only during the Approach and Landing Tests(ALT), OV-101-Enterprise was indeed placed at the lower 3ºAOA for the SCA/Orbiter Vehicle ferry flights. Enterprise had the honour of being the only Orbiter Vehicle to be carried in both the ferry(3º) and the ALT mission(6º). SCA/Enterprise flew from USA/CAN to Europe in the lower "ferry position".

Who knew that circuits and bumps were within the orbiter's capabilities?

[@TinkersWithMotherboards]

I thought I'd share the story of the day I spent landing the orbiter over and over again. In the late 90's I was working as a jr. systems administrator in a research lab at JSC that had built an out-the-windows simulator that had been used to help develop the recent glass cockpit upgrades for the shuttle. They were running some tests on the simulator and needed someone to pilot the thing to make sure it was working and fine-tune the displays, so I got tapped. I had never seen the simulator run before, and no one told me how to operate it. It included a full-sized cockpit mock-up and several projectors that ran out-the-window visuals on an at-the-time state of the art SGI supercomputer. So I sat in an accurate-to-scale cockpit flying the orbiter with a joystick and a bunch of glass-cockpit controls. The simulation started somewhere high over Florida, which I figured out by pointing the nose down until I could see the coastline. But the simulation kept restarting before I could get anywhere near the ground. Since I couldn't figure out how to land it, I started trying Immelman's, barrel rolls, etc., out of frustration. (Shout out to the original 'Ace-of-Aces' game books) It turns out the orbiter was not highly maneuverable. Finally, someone came over and said 'what are you doing', to which I replied something like 'I don't know', and they said 'here, keep the dot in the cross-hairs'. Ah Ha! A Head-Up Display! So after several more tries, I managed to start landing it, or getting close, although it helped when I was shown a few other controls, like the one to lower the landing gear. But I eventually managed to even get the landing flare down. When that got old, I got bored and tried a few other things, like doing a belly landing without deploying the landing gear, and actually managed to find a flaw in the simulator, because if I glided in smoothly enough, I could get the runway going over my head before the sim stopped. Apparently, it hadn't occurred to anyone that someone would be crazy enough to land without deploying the gear first, so the simulator didn't count touchdown as happening until the virtual wheels, which were still tucked into the body of the virtual orbiter, met the surface of the runway. So they had to go back and update the simulator to fix that. As a result of all of this, I could honestly claim in my list of useless life skills that, in an emergency, I could probably actually land the orbiter if I had to...
