That's hardly the only problem with this video. For example, Simon said something about "the missile gap" while going on to talk about the Soviet SA-2 surface to air missile (SAM). The "Missile Gap" had nothing to do with SAMs: it had to do with intercontinental ballistic missiles (ICBM). The "Missile Gap" issue had to do with which side had more ICBMs and what state of development they were in. Some intelligence assessments held that the Soviet Union had more ICBMs fitted with nuclear warheads and were growing their ICBM fleet faster than the US. Where this issue crossed paths with the XB-70 program lay in whether to put relatively short defense dollars against bombers or missiles. As for SAMs, the XB-70 would have been fast enough and flying high enough to avoid most SA-2s: the SR-71 was able to avoid everything ever shot at it. What really killed the XB-70 was the cost of maintaining a large fleet of high-tech bombers versus the cost of maintaining a smaller fleet of ICBMs. The bombers needed a lot of maintenance and the crews needed a lot of training. The ICBMs were stuck in holes in the ground and never flew anywhere. Another issue I have with this video is that NASA's research into high altitude/high speed flight wasn't covered. There was a gap between the 1966 accident and the final delivery to the Museum of the US Air Force in February 1969. According to NASA's fact sheet on this program, the XB-70 provided essential data for supersonic transport (SST) design and sonic boom research. This was critical to filling in gaps in knowledge of these questions about flight. Perhaps more interesting was the accident investigation report emerging from the 1966 crash of AV-2, and that wasn't covered at all, yet it was critical to the rapidly expanding air passenger market. It turns out that AV-2 was brought down by its own wing vortices. One of those caught the F-104 chase plane and swept the aircraft into the vertical stabilizers. Prior to that time, aircraft weren't big and fast enough to generate significant vortices, so the problem wasn't well known. But with aircraft like the Lockheed C-5 Galaxy, the L-1011 and the Boeing 747, wingtip vortices were about to become a problem. So the fact that the AV-2 crash report highlighted the problem before any of the jumbo aircraft made it into the air was significant.

[@enscroggs]

@@johndemeritt3460 The "missile gap" had to do with John F. Kennedy vs. Richard M. Nixon. Kennedy campaigned hard on the accusation that President Eisenhower (and by extension his Vice President Nixon) had neglected America's defenses, allowing the Soviet Union to significantly surpass the U.S. in throw-weight, range, and especially numbers of ICBMs. Kennedy and his handlers cleverly exploited the general anxiety of the Cold War amplified by the widespread panic caused by the Sputnik launch (4/10/57) to create a false narrative against Nixon. Eisenhower and Nixon knew the missile gap polemic was bullshit, but could not respond without compromising one of the most important secrets of the time: CORONA. American spy satellites coupled with nearly four years of U-2 overflights led the CIA to estimate the number of operational Soviet ICBM in 1960 to be "about a dozen". However, the so-called National Intelligence Estimate, a document co-authored by Congressional staffers and academics with no access to the most classified sources differed sharply, claiming the number was 500 or more. The NIE was leaked by Congressional Democrats to Washington Post columnist and Kennedy supporter, Joseph Alsop, who trebled the NIE number to 1,500 in his writings. Today the real number is known: 4. kzbin.info/www/bejne/nF7GZ3aYhbmUmqM

[@RageDavis]

Nice vdieo, but one aspect of the planes design has been totally neglected: the folding wings were not added to improve lateral stabily, that was only a side-effect, even though one most welcome. There were however two other reasons for the folding wing tips: The first one is an aerodynamic one: Whist accellerating from zero speed to mach 3, the center of lift of any aircraft moves down the centerline to the back of the aircraft. For example, Concorde had to pump fuel back and forth during accelleration respectively decelleration. Folding the wing tips down reduces the net area of the wing and therefore can be used to compensate for the aerodynamic effect of moving center of lift. The second reason however is the stroke of genius in the aircrafts design: The folding wing tips were designed to trap the aircrafts own shockwave in order to generate lift. This additional lift resulted in two benefits: 1. a higher service ceiling 2. reduced drag due to a reduced need for generating plain old aerodynamic lift, which always induces drag. Testing of the so called compression lift theory was the main reason, the aircraft was continued, after the militaries interest had dissolved.

@@ObservationofLimits In addition to other comments, this was also the last gasp of the US & the USSR focusing on high-altitude bombing as the primary means of asserting air superiority. By 1967, the USSR would introduce the MIG-25 & put the USA in full-on panic mode about the mystery fighter that could go higher & faster than anything the West had. Basically put the development of the next generation of fighters in the US into overdrive, changing strategic tack to asserting air superiority through dogfighting & controlling an airspace. The irony? The MIG-25 was made almost specifically for the purpose of catching & shooting down the XB-70.

[@markkosten]

You forgot one of the most unique features of the plane: the folding wing tips enabling what was called compression lift, so that at high speed it rode on a cushion of air that reduced drag and fuel consumption. The only other plane that was comparable was the SR-71, but this was almost as fast and had a similar ceiling, so it was in fact the highest AND fastest jet plane, ever. No. 1 was flawed in many ways and hardly ever flew above Mach 2, but no. 2 had a slightly different design and was much more stable at high speed and regularly surpassed Mach 3. Interestingly, the MIG-25 foxbat was developed to be the interceptor for this plane, and was a shockingly badly built plane that was basically a giant engine, but it was all the Soviets could do to get to the speed and height needed. The Soviets also had their own version, the Sukhoi T-4, which looked virtually the same but smaller, but it never went beyond prototype stage.

While in other videos you suggest that we let you know if we are interested in seeing videos related to the current subject or mentioned by you. Great ideas. What I suggest is if possible re-edit the later videos so a link is briefly superimposed at the point you mention it if you have since published the video in question. Or even just a graphic saying "I did it", "its done", "currently available", " check it out", or my favorite, "mission accomplished". Or whatever your preferred verbiage, phraseology, earworm, or catchphrase you devise. Good luck. PS: The added advantage to the " Mission Accomplished" version is that a quick clip from your Nimitz video could be used with the misguided banner across the Abraham Lincoln would be useful. Though it also could send the message of being a bit premature in the proclamation. Ironic, hilarious, but still on point. Maybe.

[@danbenson7587]

Riley, Nuke powered aircraft went nowhere. In a jet engine, inlet air goes through a compressor, fuel is added and burned in the combustor. The hot gas expands through the turbine and also propels the aircraft. The Nike idea was Heat was transferred from the reactor to a heat exchanger which replaced the combustor. The problem was it could not heat the air anywhere near as hot as burning fuel. End result, for the same power, was a huge, heavy engine. The research proved it would not work rather than could!

[@rileyk5628]

You gotta have some imagination and accept that there were concepts that would make great videos, even if they didn’t succeed as actual designs. For instance, I’d love to see a video about Project Habakkuk (the Ice aircraft carrier; I’m sure someone of your knowledge knows of it)

[@danbenson7587]

Riley k Sorry, I could not shake being a Mech Engineer (retired). I worked in Gas Turbines for awhile. Analysis alone would soon prove such an idea too heavy, reasons stated. At the time, the Cold War was on, and a lot of $$ spent on white collar welfare. Would not surprise that some contractor built a proof of concept nuke Plane GT. Troll the net for the B36 bomber and will find some info on nuke power planes. There have been successful closed cycle power generation gas turbines (coal fired) running helium. Current research on closed cycled CO2 gas turbines for thorium nuclear power. Another idea kicked around is nuclear particle accelerator for deep space travel. The concept is accelerate a train of individual atoms to near light speed, the reaction propels the craft. This saves launch weight.

[@randycampbell6307]

Nuclear Aircraft video, very much yes. Partially because it will end up answering a bunch of your questions, mostly because "Cold War = Cool but Crazy" is a great theme : ) BTW the main reason for not including a lot of lead shielding is because it is still an aircraft which has to have enough power-to-weight to actually get off the ground and fly, The NB-36H in which the reactor didn't actually power anything btw, was extremely heavy and took a LOT of runway to get un-stuck enough to lift off. And as you'll find out when doing the research they didn't plan on the reactor powering a bunch of electric propellers, (though arguable the most efficient system, oddly enough going in that direction got the US and UK talking about equipping the SARO Princess sea-plane with a nuclear reactor btw, the problem with electric props is the 'power-on-demand' needs which electric motors have some issues with... I digress) but by either direct cycle, (outside air flow directly through the nuclear reactor to produce thrust) or in-direct cycle (a heat exchanger is between the air-flow and the reactor) jet engine systems. Both to get the needed thrust and on-demand power and also to possibly allow supersonic flight.

[@TeaEngineer]

You should look at the XB-36 (along with the B-36 Peacemaker from Convair). It was THE nuke aircraft test platform. It was the B-52 of the Transition period from propellers to jets. It was larger and could travel (normally) further as well as more than the B-52. It was a 6 reverse-propellered with 4 jet-assisted aircraft. It did eventually get succeeded by the B-52. But it had such a fantastic carrying capacity, that it is one of the only bombers to carry a nuclear reactor into the atmosphere with the intention of using it for its powerplant. Nuclear-powered bomber, thermonuclear warhead carrier, as well as mothership (it can carry, deploy, and recover aircraft), reconnaissance aircraft (because it can do high altitude). This was the swiss army knife of aircraft, it had 22 variants during its production.
