The four ponies from the land of Earth walk down the streets of town when they see a large group of ponies standing looking at the sky. They join in and saw a streak of rainbow crossing the sky towards the ground and identify her as Rainbow Dash.
"That's awfully fast for a pegasus...." Chase says looking closer.
"I agree....it seems rather dangerous guys....." Bridget says a bit scared of what's to come. They see Rainbow Dash turning into a rainbow and immediately yelling, "DUCK AND COVER!" as they did so.
*BOOM*
A double rainboom splits the sky and causes a force of an atomic bomb. The blast demolishes ponyville and leaves four dead ponies on the ground that were killed by the rubble that came from the blast.

"As you all know, we are here because of the death of 4 ponies. They moved to this town, and were unfairly cut short of life by the double rainboom," Twilight says addressing the ponies gathered at the still-destroyed funeral area. Each pony pays their respects though none truly met the four ponies. One pony remains hidden, the rainbow-maned pegasus that caused the destruction. Ponies start getting the bodies ready to be buried when Rainbow Dash comes out of the hidden place in the crowd to come to the bodies.
"I have some words to say..." Rainbow says as she holds back tears.
"I only spoke to you guys once.....I wish I could've known you better and that I never did that double rainboom..." Rainbow can't hold back any emotion anymore even though that is very unlike her.
"I was selfish. I stole from Twilight and, in the end, all I caused was death and destruction....I'm so sorry...." Rainbow stops and goes back to the crowd to watch the burying.

Epilogue:
Bridget, Chase, Miles, and Sarah's parents searched for years but never found a trace of their lost children. Earth is under crisis as a situation similar appears in every country of the globe. The death/dissapearence of these people/ponies may have led to more than one would have though
