Footsteps of something very large…you should probably run.
A heavy boomtastic boom from far, far away.
Deeper fireball sound
Long fireball sweep
A heavy and slow heart beat
A fireball heard from afar
A 767 just flew over
The UFO is shooting a fireball…you’re going to want to watch out.
Spacey sweep effect
There goes that spacecraft again
