Dan Kreigh was the lead structural analyst for SpaceShipOne. Dan made sure that the SpaceShipOne structure was strong enough to withstand expected flight, pressure and landing loads yet light enough to make it to space. SpaceShipOne won the $10million Ansari X-prize for being the first privately built manned reusable spaceship to fly to space twice in two weeks. SpaceShipOne was designed by legendary aerospace engineer Burt Rutan. Scaled Composites, that built SpaceShipOne, was founded by Burt Rutan in 1982. Dan Kreigh has been working with Scaled Composites for almost 30 years. Dan has probably structurally analysed more different types of FLYING aircraft (14+) than any other analyst due to Scaled Composites' amazing record of producing one new type of flying aircraft every year on average. One of Dan's most recent structures is the cabin for the world's largest wingspan (385') airplane, "Stratolaunch" being presently finished in Mojave, CA.

Dan also owns and flies a Burt Rutan designed Long-EZ home built airplane. Dan is an avid model airplane enthusiast having designed and sold over 8,000 kits of the popular IFO park flyer design. Dan's current project is his own-design, two-place, 180 mph, low cost, "flying car" or "roadable airplane" that can DRIVE to the store, FIT inside an average one car garage (16.5' long) and can fly over 1,000 miles nonstop.
