I dropped an AT-TE at 13000 MPH using sun gravity. The kinetic energy of the AT-TE was about the same as a Small Nuclear bomb. Spoiler For Statistic nerds, thats the energy of... 12700 Freight Trains at full speed 37 747s at Full Speed 20 Satellites reentering the atmosphere
I remember the first time I set this type of crash up - it took me forever to do, and the entire game crashed when I tried to run it. Now, I understand the map editor well enough to get it together in minutes, and I can run it at full speed without fear!
