The Bus That Grew Wings

A small yellow bus was traveling to school
But alas it was stopped when it ran out of fuel
But then came the wings, the bus started to fly
It want up past the clouds, and the sun, to the sky

The bus started to glow as it flew past the stars
It soared past the moon and landed on Mars
Thus ends the story of the mystery case
Of the bus that grew wings and landed in space
