Harlan, who had rented a shed to Max Schüler, took over the semifinished student model in 1910. His chief architect Karl Grulich improved it, finished it – and Harlan came out with it. This Harlan-Eindecker became a successful aircraft. On 29 December 1910, Grulich thus flew his aircraft license number 46. By the end of the year 1911 several versions of this pattern were built and sold. At the end of 1913, the Harlan works had three aircraft sheds, but in the spring of 1914 Harlan was financially deadlocked. He sold his company.
At the beginning of 1914, the “Bussard-Flugzeug-Werke GmbH” emerged from the sale of the remains of the Harlan-Flugzeugwerke GmbH and had its small workshop and flying school in the shed.
The Rocket II is a modified Van’s two place RV-4. The kit to build a Rocket II from John Harmon is an extension of RV-4 kit which is purchased from Van’s. With the intended use of bigger engines the altered fuselage is wider and the length 18 inches longer. The modified wing was tested by an independent engineering facility. A unique modification is titanium for the gear legs which provide a difference in feel when landing and also doesn’t shimmy during ground operations. The HR2 is not a quickbuild kit as many builders of the Rocket prefer to be more involved in the aircraft building process and express a preference of some minor fitting and trimming. An economy cruise speed of 215 mph at 55 is average for a Rocket II with a LYC.10-540 -C4B5/250 hp. 2575 rpm. while there is one Rocket that has a 340+ horsepower and can cruise at 275 mph.

Harmon chose the long-established combination of a welded steel-tube fuselage and tail surfaces, with wood spar and rib wings. In addition, the wing may be easily removed for storage and towing. The entire aircraft can be built with hand tools except for the use of a welding rig. Mr. America’s powerplant is a nearly stock 1600-cc Volkswagen engine bored to 1650. The engine develops an honest 60 hp, to pro¬duce what is said to be rapid acceleration on takeoff to around 800 fpm at 90 mph during initial climb.

The translation of this open-cockpit sport plane’s name is “The Thunderclap” It was the airframe of this plane which was used as the foundation for “Mr. America.” Both share similar wings, fuselage, tail unit and landing gear. The wings are a wire-braced, shoulder type with two simple beam spars. As with the Mr. America, seating is for one, behind a modified Volkswagen engine turning a two-blade wooden prop.

Introduced in 1988, the Harmening High Flyer powered parachute was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category’s maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 247 lb (112 kg). The aircraft was designed to be a single-place or optionally two-seater. The base model High Flyer features an MK Superfit rip-stop nylon parachute-style high-wing, tricycle landing gear and a single 45 hp (34 kW) 2si 460-F engine in pusher configuration. Variants use other engines.
High Flyer Executive
The aircraft is built from a combination of bolted 6061-T6 aluminium, welded 4130 steel tubing and mild steel. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates sprung steel suspension. The aircraft was factory supplied in the form of an assembly kit that required 30–40 hours to complete.
All kits were manufactured in the USA, and includes the engine and 3 blade propeller. FAR 103 legal, the High Flyer Standard converts from single to two place in 10 minutes.
By 1998 the company reported that 75 kits had been sold and 75 aircraft were completed and flying, the cost in 2001 was US$9,500.

The production by Harmening’s High Flyers of Genoa, Illinois, USA, ended when the company went out of business in circa 2008.

Don Harkness was the first Australian who designed and developed a type-approved aircraft engine. The engine was the Harkness Hornet, first built in 1928 and later installed in two locally built aircraft types, the Genair and the Wonga.
The Harker Hawk PFA 003-10004 is a single-engined aircraft registered G-BDNE. An original design by Don Hawker, the Harker Hawk was started in 1973. A two seat low wing monoplane with slightly swept-back wings, it had a tail wheel undercarriage. Powered by a Continental A65, construction of PFA.03010004 was underway during 1974.
