So Far, the coolest thing that ever happen to me is when I was fighting a Terran version of ISS Enterprise A with the KM miranda.
The ship cloaked out on me, And I was in severe damage. Just out of luck by at least a split second, I fired a photon right up it's Impulse engines, and another at it's cloaking device. The enemy had also suffered a great deal of damage for out of this that both warp engines started shooting plasma.
I quickly aimed for both plasma streams to ignite it, And once the explosions reached the ship, IT TORE IT APART, AND SPLIT THE SHIP IN HALF, KILLING IT WITH AN IMENSE EXPLOSION! However, I got to close to the explosion myself, And I began spinning out of control until I Hit a nearby starbase.
After that, well, u know the rest.
