Ślęza

Ślęza (Polish; German Lohe) is a 78.6 km long river in Lower Silesia, southern Poland, a left tributary of the Oder. It starts in the Niemcza Hills (Wzgórza Niemczańskie), part of the Sudeten Foreland (Przedgórze Sudeckie), and flows near Mount Ślęża through the Silesian Lowland (Nizina Śląska) and enters the Oder in Wrocław.

The most important tributary is the Mała Ślęza ("Small Ślęza"). The most important towns on the river are: Niemcza, Tyniec nad Ślęzą, Jordanów Śląski and Wrocław.

The name probably is derived from a Silesian word meaning "wet swampy place". In a papal bull from Hadrian IV in 1155 the river is called the Selenza.

The names of the Ślęza and Mount Ślęża are both of Silesian origin, although the Ślęza is spelled with a standard Z and Mount Ślęża is spelled with a Ż diacritic - English zh.

Aero L-39 Albatros

The Aero L-39 Albatros is a high-performance jet trainer aircraft developed in Czechoslovakia to meet requirements for a "C-39" (C for cvičný – trainer) during the 1960s to replace the L-29 Delfín as the main training aircraft. It was the first of the second-generation jet trainers, and the first turbofan-powered trainer produced, and was later updated as the L-59 Super Albatros and as the L-139 (prototype L-39 with Garrett TFE731 engine).

A further development of the design, the L-159 ALCA, began production in 1997. To date, more than 2,800 L-39s have served with over 30 air forces around the world. The Albatros is the most widely used jet trainer in the world; in addition to performing basic and advanced pilot training, it has also flown combat missions in a light-attack role. Atypically, it has never received a NATO reporting name.

At the Farnborough Airshow in July 2014, Aero Vodochody announced the launch of the L-39NG, an upgraded and modernised version of the L-39.
