Why a Museum Needs a Vault

A visitor sees about a hundred objects. Behind the wall, in the reserve, there are more than three hundred. That is a normal ratio for a technical museum: display space is always smaller than the collection, and the gap only grows. Hardware sits in the reserve for three reasons. The first is the restoration queue. A Ka-27 handed over by naval aviation awaits blade restoration; the Tu-154 simulator is preserved with its hydraulic system removed. Work proceeds one machine at a time, because there is one workshop. The second reason is research. Some objects are not yet attributed: the exact type, plant or history is unknown. Until an object is described it cannot be displayed — a label under an exhibit is a statement for which the museum is answerable. The third is simply space. The Fobos spacecraft mock-up and the Krechet-94 lunar suit are entirely ready for display, but the space hall has no room for them, and thinning the existing display would be wrong: hanging density is part of the design. A closed reserve does not mean an inaccessible one. HANGAR-Z tours run daily for groups of up to fifteen, evening tours up to twelve. The limit follows from the aisles between racks and from the fact that the reserve is a working one: people are at work alongside. Researchers get access by request through the Archive section of the site. Manuscripts, drawings and photographs from the reserve follow a separate procedure: some material carries rights restrictions and is issued through signed links with a limited lifetime.
