2、port Building (OSB) I, proprietary elevators were acquired when they were not needed, because proprietary elevators are more expensive to install and maintain the elevator acquisitions should have been nonproprietary.

3、iption of Driving Event: All five elevators in the OSB I at the KSC are proprietary, even though proprietary was not required.
