the steel beams and damaged limestone pieces from the Pentagon's west wall rest atop marble blocks bearing the names and birthdays of the 68 Marylanders who died in the 9/11 terrorist attacks. Windows on the top floor of the Baltimore World Trade Center are marked with all of the names of the September 11 attack victims. Inscriptions on the marble platform, describing the events of the September 11 attacks, are arranged so that the building's shadow moves across them like a sundial. On September 11 each year, the shadow touches each inscription at the time that event occurred. The second exhibit memorializes the passengers of Flight 93 with a smooth, glossy granite block. The memorial was designed by the Baltimore architectural firm of Ziger/Snead and paid for by donations. Hurricane Isabel flooding Hurricane Isabel flooded the Baltimore World Trade Center's basement with of water in September 2003, destroying electrical, mechanical and telecommunications equipment serving the entire building, located there. The building remained closed for clean-up for more than a month after the hurricane struck, displacing 60 tenants. State ownership of building The building is owned by the Maryland Port Administration. As a result, there have been public discussions about whether it should be sold in debates over state budgets. In the "Maryland Transition" report to the incoming Governor Martin O'Malley in January 2007, the Transportation work group noted that former Governor Robert Ehrlich favored selling the Baltimore World Trade Center. Governor O'Malley chose to maintain state ownership. During the fiscal year ended June 30, 2008, the Baltimore World Trade Center incurred an operating loss of $2.3 million. This was due to an occupancy rate that had declined to 43 percent by March 2008. A low occupancy level was expected "to make it easier to sell". The Maryland Board of Public Works took two important steps in 2007 and 2008 toward improving occupancy at the World Trade Center: streamlining lease approvals and hiring an agent. In December 2007, the Board delegated its lease approval authority to the Secretary of Transportation. Meridian Management Corp. was awarded a 5-year contract, beginning on June 10, 2008, to serve as the World Trade Center's leasing agent. Meridian's contract, approved by the Board of Public Works on May 21, 2008, also includes operation and maintenance of the building.
