Aero L-29 Delfín

The Aero L-29 Delfín is a military jet trainer developed and manufactured by Czechoslovak aviation manufacturer Aero Vodochody. It is the country's first locally designed and constructed jet aircraft, and likely the biggest aircraft industrial programme to take place in any of the Council for Mutual Economic Assistance countries except the Soviet Union.

In response to a sizable requirement for a common jet-propelled trainer to be adopted across the diverse nations of the Eastern Bloc, Aero decided to embark upon their own design project with a view to suitably satisfying this demand. On 5 April 1959, an initial prototype, designated as the XL-29, performed its maiden flight.
