Martin Mattes' Aero Vodochody L-29 Delfin

Martin Mattes, of Brantford, Ontario, Canada, owns this beautiful Aero Vodochody L-29 Delfin  that is available for airshows, flybys, film and also with model Dany Ried (www.dany-ried.com).

The Aero L-29 Delfín (English: Dolphin, NATO reporting name: Maya) was a military jet trainer aircraft that became the standard jet trainer for the air forces of Warsaw Pact nations in the 1960s. It was Czechoslovakia's first locally designed and built jet aircraft.

In the late 1950s, the Soviet Air Force was seeking a jet-powered replacement for its fleet of piston-engined trainers, and this requirement was soon broadened to finding a trainer aircraft that could be adopted in common by Eastern Bloc air forces. Aero's response, the prototype XL-29 designed by Z. Rublič and K. Tomáš first flew on 5 April 1959, powered by a British Bristol Siddeley Viper engine. The second prototype was powered by the Czech-designed M701 engine, which was used in all subsequent aircraft.

The basic design concept was to produce a straightfoward, easy-to-build and operate aircraft. Simplicity and ruggedness were stressed with manual flight controls, large flaps and the incorporation of perforated airbrakes on the fuselage sides providing stable and docile flight characteristics, leading to an enviable safety record for the type. The sturdy L-29 was able to operate from grass, sand or unprepared fields. Both student pilot and instructor had ejection seats, and were positioned in tandem, under separate canopies with a slightly raised instructor position.

In 1961, the L-29 was evaluated against the PZL TS-11 Iskra and Yakovlev Yak-30 and
emerged the winner. Poland chose to pursue the development of the TS-11 Iskra anyway, but
all other Warsaw Pact countries adopted the Delfin under the agreements of COMECON.

Production began April 1963 and continued for 11 years, with 3,500 eventually built. A dedicated, single-seat, aerobatic version was developed as the L-29A Akrobat. A reconnaissance version with nose-mounted cameras was built as the L-2.

The Delfin served in basic, intermediate and weapons training roles. For this latter mission, they were equipped with hardpoints to carry gunpods, bombs or rockets, and thus armed, Egyptian L-29s were sent into combat against Israeli tanks during the Yom Kippur War. The L-29 was supplanted in the inventory of many of its operators by the Aero L-39 Albatros. More than 2,000 L-29s were supplied to the Soviet Air Force, acquiring the NATO reporting name "Maya."

As a trainer, the L-29 enabled air forces to adopt an "all-through" training on jet aircraft, replacing earlier piston-engined types. On July 16th, 1975, a Czechoslovakian Air Force L-29 shot down a Polish civilian biplane that was attempting to defect to the West.

On October 2, 2007, an unmodified L-29 was used for the world’s first jet flight powered solely by 100% biodiesel fuel. Pilots Carol Sugars and Douglas Rodante flew their Delphin Jet at Stead Airport, Reno, Nevada in order to promote environmentally friendly fuels in aviation.
