It has too much momentum for the Star Destroyers to stop it. Escape pods swarm off the battle station like spores. A few loyal souls remain to fire the weapon, but it may be too little too late.
I don't know about you, but I also want to see the moment the rock hits the Death Star and the slow, unstoppable collapse, compression and explosion that invariably occurs! Perhaps that's another piece to consider, Matt?
even though it's a different franchise. somehow, somewhere, as that spike of Alderaans mantel slams into the Deathstar like a bullet into a grape, somehow, somewhere, Char Aznable is laughing.
They spent months digging through the remains of Alderaan, but their search was not in vain, they found a massive shard of the planet, and work soon got under way.
For the next 3 months they gathered any ship they could get, and built latches for them to connect to the shard, and now that shard plummets towards the Death Star, escape craft swarming off the doomed battle station.
Leia's fist bangs the view port as she mutters "Go.", and as the shard screams past the Star Destroyer ignoring their efforts to stop it she slammed her fist on the view port even harder now yelling "GO!", and just as the shard was about to hit the Death Star, and just as it's super laser began to fire there was a bright flash like Leia has never seen. And as she staggered to her feet she wondered. "Did it work?"
