Museum of Technology The Museum of Technology is a building in the ruins of Washington , D . C . , on the southern side of The Mall . It is only a short distance away from the eastern Museum station metro exit . Layout . The Museum of Technology is one of the few more or less intact buildings in the National Mall . However , it shows clear signs of the bombings in the area ; the building is crumbling , with pillars falling out of place and visible holes in the roof , and the attractions have been heavily damaged . Several exhibits have survived the years following the nuclear firestorm of 2077 . The original plane successfully flown by the Wright Brothers ( the Wright ' Flyer ' ) is the airplane that is smashed on the floor just inside the museum . Deeper inside the museum , one can find two more airplanes . Hanging from the ceiling in the same room as the Virgo II lunar lander is a Mustang . There is another of this airplane also on display by the Capitol Preservation Society in Rivet City . In the west wing of the museum , partially buried in the rubble is an unnamed model of fighter jet ( the same model as the jets resting on the deck of the Rivet City aircraft carrier ) . By far the biggest attraction is a Vault - Tec Corporation demonstration vault model on the second floor , through which the player must go in order to reach the Virgo II lander . It serves as a demonstration of what vault life would be like and displays the various technologies used by Vault - Tec in constructing the vaults . It consists of a hallway with windows that show examples of different vault sections . The rooms of the exhibit include a bedroom , kitchen , and classroom . Next to the windows are speakers which play recorded messages . Two exhibits on the ground floor near the Delta rocket celebrate the first human space flight of Carl Bell as taking place on May 5 , 1961 in the space capsule " Defiance 7 " ( one of the main points of Divergence for the Fallout world compared to real life ) . There is a control room to the south , up the southernmost stairs in the back . Its windows are visible from the entry hall , behind a wire mesh most likely installed by Derek Remmings , the maintenance coordinator in 2077 . The maintenance computer to the east has a list of log entries by Remmings as his officious plans are thwarted one by one by his fellow employees . The museum also contains a malfunctioning planetarium in the northern section of the west wing . The program will begin playing when the Lone Wanderer enters the room but eventually malfunctions and enters a continuous loop . There is an office on the east side of the room containing a terminal for a pre - war researcher , a Nuka - Cola Quantum , and a locked gun cabinet containing various weapons and ammo . Upon exiting the office two super mutants will spawn in the planetarium entrance . Related quests . Jiggs ' Loot . In the atrium there is an unlit " Museum Information " terminal inside the translucent cowls usually used for telephones . It displays , below the usual menu items , a message from Prime to Jiggs , beginning the minor quest about a weapons cache in the security office ( west of the planetarium ) safe . Properly entering codes at this terminal and two other " Museum Information " terminals activates a password which is automatically entered when the terminal near the safe is accessed , unlocking the safe . The second password terminal is in the west wing , and the third by the rocket ; see the Jiggs ' Loot article for locations and passcodes . The immediate reward inside the safe is the key to the gun cabinet in the planetarium office , containing a missile launcher , some missile s , and 2 pulse grenade s . There is a further , greater , reward : Prime ' s corpse , with the Xuanlong assault rifle , only spawns if the three correct numbers are chosen . Galaxy News Radio . In exchange for information about your father , Three Dog requests that you do a little favor for him . You must recover a satellite dish from the Virgo II Lunar Lander in order to broaden the station ' s signal , as the one on top of the Washington Monument was destroyed . If successful , Galaxy News Radio can be broadcast over the rest of the Wasteland instead of it being limited to just the D . C . area . Appearances . The Museum of Technology appears only in " Fallout 3 " . The same Museum of Technology posters from " Fallout 3 " can be found in " " in various locations .
