I can honesty say I've had an opportunity to fly an L-39 Albatross!
My wife bought me a backseat ride for our anniversary a couple years back. The pilot performed a high speed, very low altitude pass along the runway after take-off. We then went to an acrobatic zone over a deserted industrial area and performed loops, rolls and switch backs.
I was given the stick to just lazily fly around as I wished. Unfortunately I wasn't allowed to go inverted - Damn!
The pilot finished with a 4 consecutive rolls on the way back to the airport....brown...blue...brown..blue...brown...blue..brown...blue
