Heli to the rescue (by sweetieslut)

>Heli had not been trained for such a large load,
>The waters rose quickly, no other pony would get there in time.
>It would be up to him, and him alone to save the day.
>Looking down he saw the children trying to save above water.
"Don't worry kids, I will save you"
>Lowering himself he lands on the bus, his front hooves latching onto the bus.
>The strains of his rotor whirled in his ear, nearly deafing him as he lifts the children and bus out of the water.

>The water and cold air sting the body of the young Heli
>It would be so easy to let go.
>His mind wander for a bit, his shivering cold body about defeated.
>Looking down at the verge of collapse he makes up his mind, these kids will make it
>Ice starts to form on his rotor, may other heli would have given in by now.
>He refused to admit it, even though he saw through a small lense of ice the nearby land shined bright.
>Dropping the bus down on the land he collapses nearby, his eyes freezing shut.

>A bright light awakens Heli,
"Am I de..."
>He is cut off as the warmth of a little child presses against his body.
>"You can't die pony"
>The sweet child's voice awakens your freezing mind, you realize the light is that of the bus.
"Are... Are you alright"
>You manage to blurt out through frozen lips glad you managed to save the little ones.
>The little warmth from the kid is multiplies by several others.
>Though you eventually though out, you realize you had never felt warmer then when you nearly froze to death.
