This is the Space Shuttle Main Engine (SSME). Three SSME's plus two Solid Rocket Boosters (SRBs) power the reusable Space Shuttle. Each SSME produces 375,000 lbs of thrust or a total of 1,125,000 lbs and uses liquid oxygen and liquid hydrogen as propellants.

This SSME is made of up of components of SSMEs that have flown into space. The flights have included the first four Shuttle missions, the second Hubble Space Telescope repair mission, the missions that launched the Magellan and Galileo space probes, and the John Glenn flight. The engine was donated by Rocketdyne to the Smithsonian in 2004.

1920 Service/Howe

A pair of Indiana manufacturers teamed up to produce this 1920's vintage pumper. Service Motor Trucks were built in Wabash (The "Service" name can be seen written in script underneath the seat) while Howe Fire Apparatus operated a factory in Anderson. This machine was fairly simple with a mid-mounted rotary pump with a capacity of 250 to 500 gallons-per-minute. A copper booster tank with reel and an apparatus bell are between the pump and hose body. The 20-foot length of hard sucction hose wrapped around the front of the chassis was typical of the majority of Howe rigs constructed before WWII.
