"S.T.A.R. of the Future" is a promo for the YC-15, an aircraft produced by McDonnell Douglas Corporation, designed for tactical transport. The video dates from the mid 1970’s, most likely 1976.
Series of short shots of the YC-15; landing, a tank reverses into the cargo bay, two shots of a take-off, a refuelling, and of agile handling. Slow zoom in on the U.S Air Force logo (:06-:59). Title plate (1:00-1:09). Several engineers look over technical drawings. Footage of fuselage of plane being constructed (1:10-1:22). YC-15 Number One, white in colour, is seen taking off, then a shot of it in flight (1:23-1:37). This shot structure repeated with the YC-15 Number Two, camouflaged in paint scheme. (1:38-1:55) Shots of both of these planes landing (1:56-2:18). TC-15 Number 2 is seen unloading a military jeep, then Number 1 unloads a tank (2:19-2:27). Number 1 is seen landing on a dirt strip, then driving over several basic obstacles on another runway (2:28-2:58). Thrust reverser seen opening, then various shots of Number 1 reversing (2:59-3:28). A perfectly symmetrical shot of Number One taking off from the front, then a shot of it landing (3:29-4:01). Number Two seen landing, then taking off and sharply manoeuvring to the side during take off (4:02-4:25). Slow motion shot of airdropped items being release from the cargo bay of Number Two (4:26-4:38). The planes are seen landing and maneuvering sharply on dirt landing strip, then Number One slowly pulls to a stop (4:39-5:07). Zoom out from a business meeting. Cut to a group of engineers constructing a redesigned set of YC-15 wings in a hangar (5:08-5:33). Shots from different angles of Number One with improved wing and engine design (5:34-5:57). Number Two is seen flying, then a refuelling from a plane above is seen from two different angles (5:58-6:31). Number two is seen taking off in two different environments, one an air show, another a more isolated location (6:32-6:58). A small missile is loaded into the cargo bay. A tank is driven out of the cargo bay in another location (6:59-7:17). Zoom in and out on an updated engine system for Number Two. (7:18-7:39). Number One lifts off and is seen doing a flight test with updated wing and engine system (7:40-8:26), then an over-the-shoulder cockpit shot of the pilot flying over farmland (8:27-8:50). We see flight test of Number Two with design update (8:51-9:45). Both planes seen flying at close proximity at very low altitude (9:46-10:07). Various short shots of the planes in flight, sometimes in tandem with one another or another strategic aircraft (10:08-10:54). More brief shots; number two is seen landing, a tank leaving the cargo bay, two land rovers leaving cargo bay in synchrony, an airdrop at low altitude (10:55-11:17). Number One seen taking off from a dirt strip, then flying from below (11:18-11:38). Closing plate (11:39-11:47).
The McDonnell Douglas YC-15 was a prototype four-engine short take-off and landing (STOL) tactical transport. It was McDonnell Douglas' entrant into the United States Air Force's Advanced Medium STOL Transport (AMST) competition to replace the Lockheed C-130 Hercules. In the end, neither the YC-15 nor the Boeing YC-14 was ordered into production, although the YC-15's basic design would be used to form the C-17 Globemaster III. Two YC-15s were built, one with a wingspan of 110 feet (34 m) (#72-1876) and one of 132 feet (40 m) (#72-1875). Both were 124 feet (38 m) long and powered by four Pratt & Whitney JT8D-17 engines, each with 15,500 pounds-force (69,000 N) of thrust.
The first flight was on 26 August 1975. The second prototype followed in December. They were tested for some time at McDonnell Douglas as the Boeing entry was not ready until almost a year later. In November 1976, both designs were transferred to Edwards Air Force Base for head-to-head testing. Both the YC-14 and YC-15 met or exceeded the AMST specifications under most conditions. However, the increasing importance of the strategic vs. tactical mission eventually led to the end of the AMST program in December 1979.The Lockheed C-130 Hercules would be further improved into the C-130J and remains in service.

Gold star for the guy who did the music. I want an airplane now.
Several at least. They can be kept in the garage.
The YC-15 would become the basis for the more successful C-17 Globemaster III, of which Boeing would continue production after the merger with McDonnell Douglas in 1997. The last C-17 left the Long Beach, California facility in 2015. A version of the CFM56 turbofan would power the Boeing 737NG (Next Generation) commercial airliner, as well as the Airbus A340 long-range commercial airliner. The C-17 is still in use today by the Armed Forces.
My airline re-engined our DC-8s with CFM56s. Cheers!
That wasn't a merger. The play was always to get their hands on what was left of the order book-mainly the C17-and let LGB bleed to death. which is more or less what happened and why I missed drawing a pension by seven months. The only thing I came away with was a foul weather jacket. Now it's their turn to bleed with the 737 Max.
@@1Dougloid LGB? I don't know what that means. I used to live next to the St. Charles plant (Home of the Harpoon!)
@@pauljensen5699LGB stands for Long Beach Airport (Daugherty Field), which was the main Douglas plant after World War Two. They also had older plants in Santa Monica and El Segundo.
@@MililaniJag , the result of that, of course, was the "Super 70." Here's a link to a film of the launch of the DC-8-63, which became the -73 with the CFM56: czcams.com/video/pnYuaU6gsig/video.html.
No wonder the air force didn't buy it. They came in under budget and ahead of schedule while meeting all the stated goals.
@68JCodeCougar - LOL you beat me to it! 😁👍👍
YEAH, any plane MUST go OVER BUDGET BY MILLIONS. MILLIONS FOR ALL THE PAYOFFS?
Just as Howard Hughes said.
Not true! They merely cancelled the program, issued new specs, and waited for Micky Dee to offer a far more expensive design...
I’ve read it wasn’t purchased because the Vietnam war was over. The Air Force found itself needing less airlift capacity than forecast.
The Vietnam War ended, and because there were already hundreds of C-130s, the YC-14 (Boeing) and YC-15 (McDD) programs that had been tested as replacements got cancelled as being superfluous to requirements...
Never forget my ride on the YC-15 at Scott Afb 1977
Gee, A baby C-17. Forgot how much they look alike. Cheers!!
1:10 That’s some serious armpit sweat.
I came across a book in a library, called something along the lines of Bristol aircraft future designs. This was from the 1950's. In there were three view drawings of many ideas for jet and transports. Was interesting to see designs that look like Hercules, Boeing Stol, Galaxy, Trident, DC10.
Just makes you wonder if all these aircraft constructors had the same ideas or the same design engineers.
Lots of convergent evolution in aircraft design. Nearly every commercial airliner today is a twin engine design with the engines slung under the wings. Twins are more efficient and cheaper to operate than tri or quad engine aircraft. Most of the Tri-Jets designs were a product of regulations requiring certain flight time requirements upon loosing an engine. Improvement of turbofan engines thrust and reliability lead to the Extended Twin Operations, ETOPS, which allowed twins to operate beyond one hour flying time from suitable airports. The same basic shapes prevail for military transport aircraft, low slung bodies to ease loading and unloading, high mounted wings to provide ground clearance for the engines, etc....
@@travistolbert2647 C-130, F-8 (A-7) example all very succesful high wing mono-planes.
and this led directly ti the C-17
The resemblance to the C-17 is indisputable.
“Airframe (72-1876), which had remained on Celebrity Row at the AMARC for many years, was destroyed in place in April 2012.”
I was stationed at Davis-Monthan AFB in the mid-80s. I was in the boneyard many times as part of my duties in the Water Shop.
I remember seeing the YC-15 along with the YC-14 on the celebrity row.
I have pictures of this and the YC-14 cabled to the desert at AMARC.
That music just screams "beige, bell-bottoms and sideburns!"
those were the days, when aircraft were developed on time, and on budget.
Ahem......F111! Nuff said.
@@downunderrob Vark still worked like a charm
McDonnell Douglas- meeting budgets and schedules.
Lockheed-not so much
Guess that's why McDonnell Douglas is owned by Boeing now.
@@travistolbert2647 And Boeing has been paying for it ever since! Cheers!
@@MililaniJag Atleast Boeing was able to use a retired McDonnel Douglas CEO when all of theirs were caugjt being too corrupt.
@@robertrichard6107 LOL! Get back to me when the next new MD airliner comes out!! Cheers!
You really see the C17 in it
Excellent.....Thanks
LET'S HOPE THIS YC-15 WILL RELAUNCH TRUST ME EVERYONE WOULD LOVE THIS AIRCRAFT.
Why would it relaunch. We have the C17.
Thanks for this 👍✈️
No problem 👍 Glad you enjoyed it!

Is it just me or does this remind anyone of the BAE-146? Then again the shape is a good one
Looks like the BAE-146's daddy.
Wait, so basically, the C17 was created by McDonnell Douglas ?
Yes. I forget why the program was stopped, but later on the design was modified to meet the new USAF Request For Proposal that ended up being the C-17.
What is this under budget thing they talk of???
It's a Six Smegma concept.
I'll take 3!
High wing designs will be the way of future airliners as the engines get larger and larger.
This Demonstrator made easy work for Boeing to develop the C-17, after the Merger/BUYOUT of McDonnell Douglas. It's STILL a great Airframe.
McD/D even did great work on helping develop midsize High Bypass TurboFan Engines, used almost exclusively today. Before this, they were only really used on giants like the C-5A, L-1011 and B-747
Boeing didn't develop the C17.
I have now discovered where Brazil copied the design of the new Embraer KC-390 freighter, which are very similar, despite the Brazilian model having only two turbines.
Well, at least we know the real reason it was never selected for the USAF, on time delivery and under budget. On time and under budget are something the USAF knows nothing about.
Looks odd with TF33/JT8Ds...even more so with exhaust silencers.
i would love to see the flight test footege
You just did.
3:47
I hear the NFL on CBS theme
I got 3 years cause I stole a landing.
That is one ugly tail fin

Designed by cartoonist posing as airplane designer.
Yeah it looks like an afterthought! "Oh man Bob! That's a good looking plane... But somethings missing.Oh shit a vertical stab!!!"
The commentator sounded like a bunch of non-engineers expressing their ignorance!!!!
Id like to think its like that for some reason
