It is thought that ICE may have contributed to the control problem
That's a interesting possibility, although I know pilots who have flown L-39s with a ton of ice on them. One fella, who shall remain nameless, couldn't get the canopy open after landing because it was so iced up.
The L-39 has MINIMAL ice protection. Blead air heats the engine air intake, and also the first stage guide vanes. You also have hot air to defrost the front windscreen, but there is nothing for the wings or tail.
As for my vest, well I haven't been able to find an ex-military one, so I use a photographers vest. Kind of bulky, but it works.
Again, the L-39 is an excellent airplane, but it's more warbird that private Lear Jet. I don't fly mine in hard IFR, and I try not to fly at night, especially over rough terrain.
