Personnel at the Federal Emergency Management Agency (FEMA) Region II office at 26 Federal Plaza in New York are unable to communicate with the city’s emergency command center in World Trade Center Building 7 and so Richard Ohlsen, one of the office’s employees, is sent to the WTC site to liaise with officials there. Personnel in the FEMA office felt their building shake when the first hijacked plane crashed into the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), but were initially unclear about what had happened. They were able, however, to see the second crash, at 9:03 a.m. (see 9:03 a.m. September 11, 2001), through the windows. Apparently after that crash occurs, “communications almost instantly became a problem and compromised the ability of the Regional Operations Center [i.e. the office at 26 Federal Plaza] to operate,” Ohlsen will later recall. In particular, personnel there are unable to communicate with the city’s Office of Emergency Management (OEM), which has its emergency command center on the 23rd floor of WTC 7. Mike Dabney, the senior FEMA manager in the office, therefore instructs Ohlsen to go to WTC 7, which is within walking distance, and act as an on-site liaison with the OEM there. However, Ohlsen’s departure is delayed because his colleagues are unable to find a working radio or a satellite phone he can take with him. He consequently only heads out at around 9:59 a.m., when the South Tower of the WTC collapses (see 9:59 a.m. September 11, 2001). He will change his plans following the collapse and, instead of heading to WTC 7, go to the command post at the headquarters of the New York Police Department (see After 9:59 a.m. September 11, 2001).
