I think there should be a option for rockets not to explode when crash landing in the config. People on servers could simply go in a rocket and suicide bomb a server's spawn area. When a rocket crash lands its explosion radius is huge. Servers could be griefed like crazy with precise aim even in protected areas. That's not a good thing. There needs to be something done about that, because if you ban spaceships there is no space travel, but if you don't do anything there could be large griefs.
