(From Rocket float from 'Too Many Boards!' by Harl Vincent)

The time for departure was at hand, and the shrill siren on the float warned the surrounding visitors to withdraw to a safe distance. The screaming exhaust of the vessel's rocket tubes was a thing to be feared, an incandescent blast that could wither and destroy the greatest of the ships of the lower air.

With its five hundred feet of glistening length resting in the chute, its blunt nose pointed skyward at an angle of thirty degrees, the Rocket III was a thing of beauty, a monument to the genius and scientific attainment of mankind. But, when the mighty energies were released from within, it became a monster of terrifying power, a mechanism that went roaring into the skies ahead of a trail of blinding magnificence, splitting the protesting air with a screech whose intensity was beyond all belief.
