This model rocket is the stuff dreams are made of, and sports engines so large that I didn’t think they’d gone that far down the alphabet yet (rocket motors are alphabetically-graded. Last time I checked into it, the largest was an O. This one is sporting a P, and an experimental Q sent a rocket to 100,000 feet.)

But the article above puts it best:

Placed together side by side in the aft end of the forty-inch wide rocket, the motor tubes that will house all of these rocket engines look small and insignificant. But these nine motors will provide more than 8,000 pounds of thrust—enough power to pick up a Volkswagen Beetle and throw it a half mile through the air.

Weather and equipment cooperating, this big bird will fly on Saturday, and if successful, Steve Eves will have flown the largest model rocket in history. Godspeed, Steve!
