The types of steps and missteps the Wright brothers took in developing the first practical airplane should be familiar to hackers. They started with a simple kite design and painstakingly added only a few features at a time, testing each, and discarding some. The airfoil data they had was wrong and they had to make their own wind tunnel to produce their own data. Unable to find motor manufacturers willing to do a one-off to their specifications, they had to make their own.
Sound familiar? Here’s a trip through the Wright brothers development of the first practical airplane.

Admittedly we prefer our Retrotechtacular videos to be campy, but sometimes the content is just so cool we have to give up that goal. So is the case with this series on the Wright Brothers’ first manned, powered flight.
Now there is some argument on who actually flew for the first time on earth. And that issue is touched upon right away by sharing the benchmarks used to substantiate the claim:
- The machine was heavier than air
- Carried a man
- Rose from the ground under its own power
- Flew under control without losing speed
- Landed safely at an altitude no lower than it took off
The two-part series clocks in at almost two hours. But the combination of images, video footage, and first-hand accounts makes for something incredibly interesting. The original flight happened 110 years ago this December. That doesn’t seem so long ago and it’s incredible to think that air-travel is now common in the developed world and we’re even seeing progress toward human powered flight that itself is doing the same kind of trailblazing the Wright Brothers did.

A student team has successfully designed, built, and flown a 3D printed RC plane using only $16 of plastic with a consumer-grade 3D printer (Makerbot), plus the necessary electronics and motor.
The folks over at the Wright Brothers Institute (WBI) have a great program called the AFRL Discovery Lab which brings teams of students, businesses, researchers, and government together to work on a specific challenge or opportunity.
One of the programs this year was the Disposable Miniature Air Vehicle, or DMAV for short. The student interns [Nathan, Ben, and Brian] spent the first 5 weeks at Tec^Edge designing the plane. The team went through 5 revisions before they settled on a design they believed could fly. The final plane weighed 1.5 pounds, and on its first flight… plummeted into the ground. Good thing they printed a second copy! After some more practice [Stephen] got the hang of it and was able to fly and land the plane successfully.
According to the WBI, this is the first functional aircraft that has been fully 3D printed (sans electronics) using FDM technology, and the first low wing 3D printed plane to be flown. Hate to burst their bubble, but 3D printed quadcopters have been around for quite a while!
Test flight video is after the break.
