All we remember is being knocked unconscious.
Some time passes. Slowly, one by one, we wake up. We're still alive... I think!
We can't see the outside. Did it work? Or did the gun break? Have we fallen back to Earth? Are we in outer space? The windows were covered by thick metal plates to survive the blast. It will take some time to uncover them. We don't hear any loud noise or feel any obvious forces or violent shaking. Is the capsule just sitting on some pile of rubble?
