6. Defiant
Ah, the serenity that comes with two engines: Lose one, and the other can keep you in the air. But most twins have an engine hung on each wing; if one shuts down, the pilot has to deal with a violent yaw. Rutan designed the Defiant with one engine at the rear to push, the other at the nose to pull. He built the four-place, 1,300-mile-range airplane for himself and decided later to sell plans. Very few were built; one was recently offered on the Internet for $85,000. (In 1984, plans sold for $490, and the cost of construction was estimated at $40,000.)
7. Long-EZ
Rutan’s best-selling homebuilt, the Long-EZ is a pumped-up VariEze with a range of 2,000 miles. Dick Rutan and test pilot Mike Melvill flew two around the world in 1997 (the year that John Denver crashed his and died). In 2001, XCOR Aerospace replaced the pusher engine with a rocket, and seven years later, former NASA astronaut Rick Searfoss flew a demonstration of the EZ-Rocket at EAA’s AirVenture fly-in to promote a league for rocket racing, which never caught on.
8. AD-1
After the Quickie Aircraft Corporation, Rutan’s next customer was NASA. The agency wanted to experiment with an oblique wing, which, according to the late, ingenious Robert T. Jones, an engineer at the agency’s Ames Research Center in California, would experience less drag at transonic and supersonic speeds. At low speeds, the wing was perpendicular to the fuselage; as the airplane gained speed, the wing pivoted up to 60 degrees. Research pilots at NASA’s Dryden Flight Research Center at Edwards, California, flew the AD-1 (named for Ames-Dryden) 79 times.
9. AMS/OIL Biplane Racer
Rutan designed the race plane to compete in the biplane class at the National Championship Air Races in Reno, Nevada. In 1982, the customer, Danny Mortensen, set a speed record of 235 mph in the airplane, which shared characteristics with the Quickie but was larger and 150 mph faster. In 1983, Mortensen crashed it during a race while flying at 200 mph. The aircraft was lost, but the pilot walked away.
10. Next Generation Trainer
In 1981, to get flight test data to support its proposal to the Air Force to provide a light jet trainer, Fairchild Republic hired the Rutan Aircraft Factory to design a 62 percent scale version of what would become Fairchild’s H-tail T-46 Eaglet. Rutan designed the model, procured two small jet engines (from Ames Industrial Corporation, which had built the same engine for the BD-5J microjet), and conducted an eight-week flight test program. Fairchild won the contract, but after only three were built, the program was cancelled.
11. Grizzly
The Griz failed as a bushplane; its low wing made it unsuitable for landing anywhere but paved runways. It succeeded, however, as a research project to test the performance of high-lift flaps on tandem wings and techniques for composite construction. Both Grizzly wings used the VariEze’s styrofoam-with-fiberglass-skin construction, but the booms’ skins were PVC core with fiberglass facings. The large wing area and flaps gave the Grizzly the capability for short takeoffs and landings. In a way, the Grizzly anticipated the Voyager round-the-world aircraft: In both, the booms that functioned as torsional braces between canard and wings doubled as fuel tanks.
12. Solitaire
In 1982, Rutan’s canard (of course) sailplane with a glide ratio of 32 to 1 and a retractable engine won the 1982 Soaring Society of America self-propelled sailplane competition, as well as a society award for outstanding design.
13. Microlight
Designed for Colin Chapman, the founder of the British sports car company Lotus, the 300-pound Microlight had side-by-side seating for two and a 25-hp engine. Chapman died the day before the prototype flew, and Lotus eventually discontinued development.
14. Starship
One of the first projects undertaken by Scaled Composites was an 85 percent scale model of what would become the Beech eight-passenger, twin- turboprop Starship with a variable-sweep canard (see “Beached Starship,” Aug./Sept. 2004). Though aviation journalists loved it—“the most exciting aircraft to emerge from the Beech stable,” crowed the British magazine Flight International in 1986—Beech sold only 11.

And those are only the "white" aircraft....

there were other "black" D.O.D. projects i presume?
I remember at one Oshkosh someone bolted a rocket to a long EZ for a "Rocket EZ" - not sure what became of that. MIKE MASSEE OF XCOR REPLIES: The EZ-Rocket is currently here in our hangar at Mojave. The EZ-Rocket was our first manned, rocket powered aircraft and we are proud of its heritage. Our current intention is to donate it to the Mojave Transportation Museum. The museum folks are currently raising money for a
museum building.
The EZ-Rocket flew a total of 26 times under rocket power. The vast
majority of those flights were under the capable hands of Dick Rutan, and
later retired NASA astronaut Richard Searfoss, XCOR's current factory test
pilot. Dick's long time friend and 'stick and rudder pilot' Mike Melvill
also flew the EZ-Rocket as a guest pilot on one flight.

Great story idea, poor execution. I have not memorized all of Rutan's planes and a photo of each one with the description would have made this article much more informative.

Rutan's greatest creation may actually be something intangible: the corporate culture at Scaled Composites. Being personally creative is admirable. Building an environment in which others can continue to be creative when the founder has left is outstanding.

I met Burt not long ago at Oshkosh this year. A passing meeting but a treat for me as I had wanted to meet him for many years. As a builder and flyer of one of his designs, a Long EZ, I can attest to the exponetial gain in performance and range his design has achieved, a fact that is evident in all of his aircraft. I flew mine over 1000 NM at fuel consumption equal to many cars, but at 180 MPH. The key for me in his genius is simply the overiding belief that you don't have to follow the crowd and stick to familiar concepts and design. I have no doubt he will surprise us more now he is free to be independent once again.

Should have mentioned the BiPod in the pictures does not have the propulsion system installed yet. When I read the article I was very confused because it obviously doesn't have any propellers or inlets or anything on the airframe. Only after digging online I found they are going to use 2 electric motors on the horizontal stabilizer and 2 electric motors on the wing, all driven from a hybrid power system. So far it has only hopped into ground effect by using its electric powered wheels to roll down the runway. Sidenote- Meeting Burt Rutan in person at the 2010 AMA show was one of the highlights of my life! EDITORS' REPLY: A clarification was published in the Letters section of the following issue.

This is to Burt Rutan:
I found a lapel pin that looks just like the Famous Solitaire; any info about it would be great. Thank you for your time. David
