Okay, I visualized this lots but it doesn't work somehow. But I have a chellenge that WILL WORK. It's not too hard, and I've done a test flight of it and even posted the video on YouTube so I know it can be done. Build a cart and mount a small range icbm on the back. 10 points for every km it travels from the cart 10 for every 100m/s above zero its traveling when it impacts No part limit 1 stage rocket (cart *decoupler* rocket) only Your choice of solid or liquid fueled Only one rocket engine of either type (excluding seperatrons) No rcs Flap limit 3 No debug toolbar I would recommend starting off slow with a liquid engine and then throttling up once your about 100m away for it to look remotely similar to a trident rocket. Really sorry, will test my challenges from now on.
