Henry J. Kaiser was a world leader in shipbuilding, associated primarily with the prefabricated Liberty Ship of Second World War. In 1942 Kaiser proposed construction of 5,000 transport flying-boats for troop carrying. Lacking aviation experience, he formed a joint company with Hughes Aircraft, Hughes to undertake design and Kaiser construction of the Hughes-Kaiser HK-1, the world’s largest aircraft. In November 1942 a contract was signed for three aircraft, one for static test and two for flight. By 1944 construction of the first was still at the preliminary stage, and the U.S. Army and Navy withdrew technical assistance. The contract was reduced to one aircraft; Kaiser withdrew, and thereafter the design was called the Hughes H-4 Hercules.

Just Aircraft
Caldwell, Idaho, USA.
Just Aircraft was founded in 2002 when aircraft designer Troy Woodland left his position at Flying K Enterprises, manufacturer of the Sky Raider kit. Troy wanted to design a plane of his own. He met Gary Schmitt at an air show and Gary wanted a plane with many of the features of the new Escapade.With Gary’s backing they collaberated on a design.
The Escapade has a huge luggage compartment, a more roomy cabin , and a simplified wing-folding mechanism that avoids the need to remove control linkages.
Soon after the Escapade came the Highlander, a more rugged plane that was the bush airplane they wanted. The Highlander Debuted at Arlington in 2004, and by 2010 dominated Just’s sales by three-to-one aircraft sold .
In 2004 the company relocated to Walhalla, South Carolina, into a state of the art production facility with its own runway. This was a time of serious growth for Just Aircraft, when materials buying and costs analysis became implemented, when marketing, accounting, and all other true “front office” needs of the growing company were founded.
Over 170 kits had been shipped worldwide: including England, France, Spain, New Zealand, Canada and Equador. Sales are running about 50/50 domestic and export.
In addition to selling kits, Just Aircraft offers customers a build assist program, where they can construct their plane in the factory, or the Company will build 100% of the plane in accordance to the customers specifications.

Junkers Larsen
John M. Larsen immigrated to the U.S. in 1892 from Denmark. As an engineer he designed, produced and sold cooling machines in the U.S.A. In 1919 he intended to sell U.S. aircraft in Denmark, but during his stay in Europe he also saw the Junkers F13 and was interested in selling the Junkers F13 within the USA. Together with Junkers he founded the Junkers Larsen Corporation in 1920, which was responsible for the marketing of Junkers aircraft in the USA. Larsen managed to sell some of the modified F13 as JL6 to the U.S. Army and to the U.S. Postal Office. But due to a series of crashes the JL6 was grounded by both. Larsen also converted one JL6 to a war machine as JL12, but the U.S. Army was not interested in this aircraft and the joint venture was stopped after a few sales, in 1920.
