Arthur Stentzel of Hamburg-Altona, Germany, began experimenting with gliders and ornithopters in the early 1890s. In 1896, he demonstrated his flapping wing flying machine at Berlin. The Stentzel machine had cambered bird-like wings of 6.5 m. wingspan and a rounded cruciform tail. It was powered by a carbonic acid engine mounted forward and below the wings. The flying machine ran along a horizontal wire, off which it lifted when in motion. The machine achieved a speed of 4.5 m/s.
The Stellar Astra is an American ultralight trike that was designed by Allistair Wilson and produced by Stellar Aircraft of Bloomfield, Indiana. When it was available the aircraft was supplied as a complete ready-to-fly-aircraft. As of 2013 the company appears to be out of business and production complete.
The Astra was derived from a P&M Aviation trike design and intended to comply with the US light-sport aircraft category.
The Astra features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.
The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 34.4 ft (10.5 m) span wing is supported by a single tube-type kingpost and uses an “A” frame weight-shift control bar. Powerplants that were factory available were the twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 503, the four cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912UL and 100 hp (75 kW) Rotax 912ULS and the twin cylinder, air-cooled, four-stroke, dual-ignition 60 hp (45 kW) HKS 700E engine.
With the HKS powerplant the aircraft has an empty weight of 485 lb (220 kg) and a gross weight of 960 lb (435 kg), giving a useful load of 475 lb (215 kg).
The aircraft was produced under contract for Stellar Aircraft in India by Albatross Flying Systems, who also marketed the design in Asia as the Cruiser. In 2011, The Astra sold for US$23,495 with the HKS 700E engine.

Inflated outdoors on 18 June 1857, John Steiner at Erie, Pennsylvania, began the first attempt to fly to Canada across Lake Erie.
Swiss pioneer Carl Steiger-Kirchhofer (1856-1946) made some flights with this parabolic wing tail-less glider in 1891.
Swiss pioneer Carl Steiger-Kirchhofer (1856-1946) made some flights with this parabolic wing tail-less glider in 1891. In the same year he published the booklet “Vogelflug und Flugmaschine”, in which he proposed several very designs with surprisingly modern-looking features. He continued with other projects, such as a 1908 underpowered biplane and several studies of bird flight and bird models, including wind tunnel experiments.
The Steger Hornet was a 1982 hang glider.
