Pilot killed in Iowa air show crash

15. You description is relative and I am not sure most aeronautical engineers would agree with you.

Unstable is better used for airplanes that require an active control system like the Wobbly Goblin (F-117), aircraft that without active and continuous control inputs would diverge. Yes an L-39 is less sedate that the plodding light aircraft designs of the late 50s/early 60s, but so are most LSAs, which are rapidly becoming the dominant trainers for GA. For example, compare a Remos with 150 or 172. Those that used to whine about the "aggressive handling" of the GA Grumman line would be in shock today.

I have several dozen different aircraft in my logbooks, including the Albatross. It was not particularly unstable. Controls are light, but the aircraft does not have a strong tendency to diverge. It was a knock off of the T-38 and handles much like it in many ways.
