Kamikaze pilots took many lives and caused a lot of destruction in the latter part of WWII. In IL-2, some of my favorite missions include elements of Kamikaze (for AI pilots, not human).
So I agree with Alien that it would be great to have a more dramatic effect tied to Kamikaze attacks.

As a mission builder, I always wished there was a 'Kamikaze' setting. I like to arm the AI with a bomb, which seems to inflict more damage to the ship. However, this also adds ammo to the plane. Consequently, the Kamikaze pilot, if attacked, will drop his bomb and try to dogfight.
In my 'Kamikaze' setting, I would be able to load a bomb with no ammo (the AI won't dogfight without ammo) and the AI would not be inclined to stray from it's intended mission.
