First of all let me say it's been a while before I could publish these photos (due to some publications). In June 2010 I had the opportunity to take some in-flight photos of the aircraft and helicopters flown by CLV, the company that provides flight training for the Czech Armed Forces.
CLV operates six aircraft types: the EV-97 (only used by instructor pilots), L-39C Albatros (jet pilot training), L-410UVP Turbolet (multi-engine training), Mi-2 Hoplite (rotary flying training), Mi-17 (for future Mi-17/24/35 pilots) and Z-142C-AF (basic flying training). Noteworthy is the fact that all four fixed-wing aircraft types are built in the Czech Republic (by four different manufacturers!). Unfortunately only one Mi-17 was available and it was our photoship, so no pics of the 'Hippo'.
Apologies for the boring head-on shots..
