* Confirmed, an F-1 engine stands tall [1] outside Rocketdyne corporate HQ on Canoga Ave just north of Victory Blvd in the San Fernando Valley of Los Angeles. One can walk right up to the engine and have a gander; it's 18 feet tall. You can admire the maze of cooling pipes on the upper half of the nozzle and imagine the heat and roar. * In decades past, during development of the Apollo space program, Rocketdyne tested engines at its Field Laboratory test facility in the Santa Susana Mountains a few miles West. The sustained outdoor roar of those engine tests was audible better than 7 miles away. Source: My elementary school classmates, blase about the whole thing, saying "Oh, that's just Rocketdyne testing again". * Lots of facility pictures of several of the Rocketdyne facilities (with engines under assembly) in the Rocketdyne Archives [2] * It's a safe bet the name "Rocketdyne" would be a portmanteau of "Rocket Dynamics". * Some rocket equations and stability discussion at [3] [1] http://www.dailynews.com/ci_21138479/pratt-whitney-rocketdyne-sold-sacramento-based-gencorp-550 http://www.dailynews.com/ci_21138479/pratt-whitney-rocketdyn...
