Wills Wing Talon. The Wills Wing Talon is an American high-wing, single-place, hang glider that was designed and produced by Wills Wing of Santa Ana, California in the early 2000s. Now out of production, when it was available the aircraft was supplied complete and ready-to-fly.

Design and development
The Talon was designed as competition-level glider. It is made from aluminum tubing, with the double-surface wing covered in Dacron sailcloth. Its wing is a topless design, lacking upper rigging and the supporting king post. The nose angle is 132°.

The models are each named for their wing area in square feet.

Flexible debris-resisting barrier. A flexible debris-resisting barrier is a structure used to mitigate debris flows or to contain flow-entrained woods.  These structures mainly consist of  interconnected metallic components (cables, posts, shackles...). Flexible debris-resisting barrier are derived from rockfall barriers and were first proposed in the middle of the 1990s in the USA.

In torrents, flexible debris-resisting barrier constitute a sound alternative to check dams for containing debris flows.

The main components of flexible debris-resisting barriers are:

 An interception structure, made up of a principal net with metallic cables, wires, and/or bars and additional layers, usually a finer mesh than the principal.
 A support structure made of metal posts, to support the interception structure.
 Connection components (also called brakes), which dissipate energy from the barrier into the ground and/or foundation.

These barriers are often installed in torrents bed to intercept and contain flow-entrained granular materials or woody debris. In their simplest form,  flexible debris-resisting barriers only consist of an interception structure. When installed in larger channels, the barrier also includes a support structure.

Castel C.34 Condor. The Castel C.34 Condor was a French high performance sailplane. Two were built and one at least served French gliding clubs from 1935 to the outbreak of World War II in 1939.

Design and development
The high performance Condor was financed by the Toulouse aero club Les Ailes (Wings) and designed by R. Castello for the use of J. Thomas, the director of the Black Mountain Regional Centre.

It had a one piece, cantilever high wing, which was straight-edged and strongly tapered (taper ratio 0.37) to roughly semi-elliptical tips. It had a single spar structure with a leading edge torsion box. Long, narrow ailerons, divided into two parts, filled the entire trailing edge; these could also act as camber-changing flaps for low speed flight.

The Condor's oval section fuselage was built around three longerons, two in the upper part and one, in the keel, which extended rearwards only as far as the rubber sprung landing skid, ending under the trailing edge. It was covered in stressed birch plywood. The forward fuselage was deep, with the wing on top and the single-seat cockpit ahead of the leading edge under a removable wooden cover with broad framed windows, limiting the pilot's view. Behind the wing the fuselage was slimmer and tapered to the tail, where a very small triangular fin carried a balanced rudder with an upright leading edge but which was full and rounded aft. The narrow tailplane, mounted forward of the rudder, carried balanced elevators.

Operational history
The contemporary French journal Les Ailes first described the Condor in a June 1934 article that included images of the almost complete aircraft, suggesting it first flew about that time, though one modern source dates the aircraft from 1933. There is one modern report that the Condor crashed and was destroyed on its first flight, though contemporary sources do not mention this event. A second example was constructed by the Aéro-club de l'Est at Nancy over the winter of 1934–1935; they named it after one of their members, Jean Schmitt, who had died in a flying accident that spring. One improvement was a cockpit canopy with increased window area and better visibility. It remained active in the summer of 1937, flying from the nearby Plateau de Malzéville. In early 1939 it joined the L'Espoir Aeronautique at Sarreguemines, who renamed it in memory of a local (Lorraine) pilot, Albert Martin. It was active over the summer, but was seized by the German forces when they invaded France in 1940.

Al Basra-class offshore support vessel. The Al Basra-class offshore support vessel (manufacturer designates as RiverHawk OSV 60) is a  multi-function offshore support vessel, providing a wide range of capabilities from command and control, to support and protection of oil/Gas installations, to acting as a "mothership" for patrol boats. Vessels of the class are operated by the United States Navy and the Iraqi Navy.

Designer and naval architects 
International Maritime Consultants (IMC) was responsible for the functional design of the Iraqi Navy Al Basra class 60 metre OSV. The original design draws heavily from the offshore support vessel sector, since the boats were designed to conduct both maritime security operations and offshore service tasks.

IMC is an independent naval architecture consultancy based in Fremantle, Western Australia, providing a comprehensive range of naval architecture, marine engineering and project management services to the global marine, maritime and offshore industries.

Features and capabilities

Troops transport
Al Basra class ships can accommodate dozens of troops including Marine Commandos, SCUBA divers or transport support for crew changes and resupply to the platforms. The well deck accommodate two Fast attack boats and gives the vessel the capability to intercept suspicious vessels, search and rescue and landing troops on shore.

Support
The Al Basra class is constructed and fitted to accomplish a variety of jobs. The vessel is equipped with a firefighting capability and fire monitors for fighting external fires at sea.  Also, the vessel is equipped with oil containment and recovery equipment to assist in the cleanup of a spill at sea. In addition the vessel has a towage capacity of 3150 BHP.

Patrol vessel
The Al Basra class is a blue water vessel operational and maneuverable in very difficult weather conditions, the vessel can accomplish all the mission of an offshore patrol vessel. The vessel has the capacity to acting as a "mothership" for small patrol boats and has the mission to provide logistic support from repairs, to crew provisions, to refueling.

Armament
Ships of the Al Basra are supplied with one 30 mm MSI Seahawk   for air defense and naval gunfire. They are also equipped with four 12.7 mm M2-HB Browing machine guns and six M240 light machine guns.
