Back when the YC-14 was in testing, Air Force Magazine and Aviation Week & Space Technology ran countless articles about it. I was very disappointed when the program was canceled. Fast forward to 1987. I'm on my honeymoon in Tucson, AZ, and we're driving around the perimeter of Davis Monthan when I spot the tail of a YC-14 sticking up from a chain-link enclosure across the road from Davis. The gate is open, so I pull in to . . . what would become the Pima Air Museum. At that time, they were just beginning to pull the collection together, and there were acres of amazing prototypes that I had thought were all lost to the scrappers. Included in this were the YC-14 prototype and the YC-15. My wife and I spent two days rooting around there. Pima is much better organized and built today. There's an indoor hall filled with interesting aircraft, and the outdoor displays have signs and guides. If you're interested in getting up-close to some of the most significant airframes of the last 75 years, Pima needs to be on your list.

A key value in the An-72 and the YC-14's unique engine mount design meant that they could use rough airfields and also use fields or other open, unprepared areas without worrying about FOD ingestion.

[@KF99]

Interestingly this concept proved to be a major disappointment - in case of An-72 it was very difficult to handle in case of engine failure, because it wasn’t only thrust asymmetry, but also a lift. STOL capabilities were quite limited and mostly achieved by high thrust to weight ratio. And this engine placement caused lots of drag in cruise flight - there was an An-74TK-300 with conventional underwing nacelles, it proved to be much more efficient, only 3 were built, and, interestingly, one of them was Gaddafi’s personal jet.

[@andrewtaylor940]

It often gets overlooked what an astonishing feat in all of human history, the development of the US’s airlift capabilities during WW2 was. especially in the Pacific. They literally shrank the globe in the span of just 2-3 years. They went from needing weeks to move men and materials across the oceans, to in some cases hours. There is a famous story told by a German officer. That when he and his men captured an American soldier in France some time after D-day, they found in his pack a fresh chocolate cake. Still in the package sent from home. He said that was the moment he knew that Germany would not, could not win. His Army could barely send them food or ammo, across a few hundred kilometers. And here was this lowly American Private. And for him the American logistics could send a chocolate cake to a battlefield halfway around the world. And deliver it still fresh.

I went to Boeing in the mid 1970s to deliver a GEC 905 computer they were using to develop the software for the flight control system to control the planes engines in a takeoff system failure. The lift generated by the wing was not just from forward motion but also from engine exhaust gases blown over the wing flaps due to the engine being mounted on top of the wing. I'm not an aeronautical engineer, I was a service engineer for the GEC 905 computer installed at Boeing for later engine flight management control software. What a great plane it was, it had not flown when I was there and I just loved the time I spent there. The hangar it was in was the hangar Boeing had set aside for their SST development, the walls had load of posters of the proposed plane, shame the project was canned. Must be nearly 50 years ago I delivered the 905 computer to Boeing, the 905 was delivered to the hangar, powered it up and it passed all the tests straight away. Those were the days, such fun with those early computers. Digital, mainly Texas SSI chips, I seem to recollect, 18 bit architecture, processor cycle time around 1 micro second. Those old computers used to fail every now and then with all those edge connectors utilised. Over the years I worked on them I found at least two 16 pin DIPS (dual in line package) not actually soldered in at all!!! It is strange how people today often think that digital PCB based computers did not exist 50 years ago, well they certainly did, I along with many others worked on them!! Cheers, John.

[@Paladin1873]

One of my ROTC instructors came to us directly from the C-141 product improvement program that resulted in the B version (which my younger brother would later serve aboard as a navigator). He told our class that when he began work on the upgrades he encountered a problem engineers were having with a lubrication oil delivery system. Someone had decided the plane needed to remain airborne over 24 hours, so this required developing a reserve oil reservoir and the means to pump it where needed. He was a pilot, not an engineer, but he quickly realized the team was designing a Rube Goldberg device. He pointed out that there was no place in the world where a C141 would have to fly that would take 24 hours to reach, so why were they wasting their time on this project goal? The powers-that-be eventually agreed with his logic and the entire system was scrapped, saving weight, cost, and sanity.

[@mikenodine6713]

And the nuclear cruise missile launch platform concept was moved from the 141 to the C5 Galaxy instead. The C5 was far better equipped for that mission, not just the several days of continuous flight from aerial refueling, but the bunk beds and coffee maker built in just behind the cockpit for the relief pilots to rest between inflight rotations on and off duty. That was the real reason for the 24 hour mission/loitering capability requirement. Whether any C5's were actually equipped with nuclear cruise missiles or not remains classified to this day as far as I know.

[@mikenodine6713]

You can google "Rapid Dragon palletized munition system" if you don't believe me about the 141 and the C5 cruise missile launcher platform concept development program. They also studied equipping a 747 as well back in the 1970's. Rapid Dragon is the same concept program being developed today for the C130 and the C17.

[@Paladin1873]

@@mikenodine6713 No, we never put any nuclear armed cruise missiles aboard a C-5. By the time the cruise missile program came along we had long since stopped flying with nukes aboard our aircraft (Chrome Dome missions) because we had too many Broken Arrow incidents. We did once air drop a Minuteman missile out of a C-5 and successfully launched it. It was largely a publicity stunt intended to let the USSR know we had such a capability if we wished to develop it further. I've little doubt the concept scared the hell out of some Soviet war planners.

A case of French muddled thinking. America did not make that mistake with Khe Sanh. The Soviet Su-25 looks very similar to the failed rival to the American A-10.

I was pretty excited making the discovery, I had tried to get inside the fence to get a close look but it was a Saturday afternoon with only the guards present so I was not able to get in.

[@gort8203]

The video does not mention the risk involved with reliance on upper surface blowing for lift during STOL operations. If an engine fails during STOL flight near the ground the loss of lift on that side will probably be uncontrollable. I would not want to fly this aircraft at STOL speeds unless every occupant was sitting on an ejection seat. Combat aircraft that use engine bleed air for low-speed lift, such the F-104 and A-5, had ejection seats. Two engines can increase the risk in STOL operations in lighter aircraft due to control issues. As an example, if an OV-10 engine failed suddenly during an STOL takeoff the aircraft was below Vmc and would likely crash, hopefully straight ahead IF the pilot reduced power on the operating power engine immediately. Therefore USAF restricted normal operations to takeoff and approach speeds higher than Vmc unless STOL was absolutely necessary

You mention Boeing's YC-14 unique engine-blown wing which is called the Coanda Effect,. What was truly interesting about this AF program is that the YC-14 and YC-15 had two completely different and advanced wing technologies that had never been flown on aircraft of this size and weight. Boeing's competitor the McD-D YC-15 used a supercritcial wing which some argued, would lose it's effectiveness and would be hard to maintain when faced with the dirt, dents of military field use. However others argued that the mechanical complexity of Boeing's YC-14 blown wing would also present maintenance problems. In the end and after the program ended, it was the McD-D XC-15 that evolved into today very successful C-17 Globemaster II which features a supercritical wing.

[@daigriffiths399]

Digital engine readouts... they look very familiar. Taking 'transport aircraft' to include civilian stuff, Lockheed's L-1011-250 (1976) had them for Delta Airlines. I think some L-1011-200s (1975) (Air Canada and Saudia) also had them. I have pics of two of these aircraft with a SECAL of 9L-LDN (I think - it's difficult to read) and 3D-NEG. I'd guess that Boeing and Lockheed were buying from the same instrument manufacturer but on the timing, Lockheed's TriStar got there first.

[@LeonmitchelliGalette]

11:00 An-72 - His look is dictated by environments in which it should be used - short and rough runaways. That's why engines high up, from dust and stones from the ground. And engines placed slightly above wings to exploit coanda's effect to make shorter run to take off. It's just evolution of An-26. And works on An-72 started in 1972.

Jet engines mounted forward and above a wing blow the speed of air over the wing - so it gives a true huge vertical vector, especialy with great flaps bended to the ground. This is the Coanda effect, named after this Romanian Engineer (Charles Coanda) who dared testing a jet engine in 1910, invented the flaps-in-tail of the space shuttle etc. French Breguet 941 used this principle just before the very cool and efficient YC14

If the project had coincided with the creation of US SOCOM, we might have gotten an MC-14. The STOL capabilities couple with is load capacity would solve a lot of problems providing special operations needs for rapid insertion and logistic support.

Impressive short landing! Must still be a record?

Great work -- thank you!

The Soviet didn’t need to spy on the American aviation industry. All they needed was a subscription to Aviation Leak and Space Technology.

They did have subscriptions to both. As well as all major US news papers. I'm sure. Kennedys famous speech to media execs is proof of this. The KGB stood outside North American Aviation for weeks, and took photos of the Vigilante prototype, the inspiration for the Mig-25.

I'm pretty sure they had a subscription, actually several.

@@Beemer917 Why? It’s cheaper just to get a library card and visit their magazine rack

I miss those Strategic Air Command colors. Such a good looking livery.

A video about the A-10B Night Obseversation Gun Ship program would be cool.

Nice one, Ed.

That's a new one for me - never knew it existed.

I learned about this plane recently because I found a special silver pin issued by Boeing of it

Victoire US au Vietnam ? Et quid du concept "d'aile soufflée" mis au point sur le Breguet 941 et qui largement "inspiré" les ingénieurs de Boeing ?

Nice story. I like how it ended.

In 1964 the U.K we’re working on a STOL transport aircraft powered by four Rolls Royce Pegasus engines. Never flew due to the new British Labour Government . Article on the above appeared in the 1976 RAF year book.
