Eight L-39Cs of the Slovak Air Force White Albatrosses demonstration team, in formation with a MiG-29, arriving at RAF Fairford for the International Air Tattoo '95, in July 1995.

Prototype L-139 in an 'air superiority' grey camouflage scheme and sporting low visibility markings, during GSh-23 cannon trials. Note that the rear cockpit is filled with trials equipment, leaving no room for an observer.

This view of the prototype L-139 clearly shows the overwing engine air intakes. Although carrying two underwing fuel tanks it has a greater range on internal fuel than any of the L-39 variants.

Developed during the mid 1970s, the L-39ZO had simple ground attack capabilities with provisions for a belly-mounted 23mm GSh-23 cannon and four underwing pylons. This variant was exported to four countries. 222 being one of 52 L-39ZOs delivered to East Germany.

This view of the prototype L-139 clearly shows two of the underwing pylons (it has provision for four 'wet' pylons), the ventral gun and deployed underwing airbrakes.
