Here's the Black Arrow: Download: http://www./download/927s0io552l9e9k/Black_Arrow.craft The second stage will twitch a bit after first stage separation.
Further tests show that it has great recoil force. It can throw an Aeris 3A a couple meters from its original spot and tore it to shreds if the plane is within a meter of the bomb (it should be much more effective in space).
Well, it's not very effective in the atmosphere. Air resistance and gravity is a problem. It also has a projectile in the middle that flies out at really high speeds.
