The wind load on an ordinary day:
Thomas Eagar and Christopher Musso, “Why Did the World Trade Center Collapse? Science, Engineer and Speculation,”
JOM,
53 (12) (2001): 8–11.
It looked as if the structural engineers:
Leslie E. Robertson, interviews by Jim Dwyer, February 28, 1993; March 1994; see also, James Glanz and Eric Lipton,
City in the Sky
(New York: Times Books/Henry Holt, 2003).
So they did what humans do:
Jim Dwyer, Eric Lipton, Kevin Flynn, James Glanz, Ford Fessenden, “Fighting to Live as the Towers Died,”
New York Times,
May 26, 2002. A comprehensive survey by the
Times
of post-impact communications from the two towers found that while hundreds of people probably died on the 15 floors impacted in the towers (94 through 99 in the north tower, and 77 through 85 in the south), that was less than half the area where people were trapped, which included the top 19 floors of the north tower and the top 33 of the south tower. Virtually all 658 employees of Cantor Fitzgerald who died survived the initial impact, as did 69 people in Carr Futures; 66 in Sandler O’Neill, and many of the 176 who died from Aon.
At a stairway landing:
Details of Beyea’s and Zelmanowitz’s relationship and their movements that day are based on interviews by Kevin Flynn and Lauren Wolfe with Beyea’s nurse, Irma Fuller, and his mother, Janet Beyea; Zelmanowitz’s brother, Jack Zelmanowitz; Beyea’s wife, Paulinita; several rescuers who saw them that day, including Fire Capt. Jay Jonas and firefighter Rich Billy, Port Authority police officer David Lion; civilians in the building, including Keith Meerholz and Patricia Cullen.
Chapter 4: “We have no communication established up there yet.”
His message went nowhere:
Timing and futility of the evacuation order over the public-address system is a finding of the National 9/11 Commission, Statement 13, May 2004.
Even the simplest advice:

His first message began at 8:46:43:
Time of Pfeifer transmission from Manhattan dispatch tape 432, September 11, 2001, job 1-44. Time of impact from National Institute of Standards and Technology, “December 2003: Public Update on the Federal Building and Fire Safety Investigation of the World Trade Center Disaster,” Special Publication 1000-4, p. 13.
They were both low-key commanders:
Details of the brothers’ lives were reported in “Portraits of Grief,” by Jim Dwyer,
New York Times,
November 25, 2001, and in “‘He Was a Quiet Guy Who Made a Difference,’” by Jennifer Smith,
Newsday,
November 18, 2001.
Still others were assigned floors:
The operational details for the first few minutes were derived from several interviews with Pfeifer and Deputy Chief Peter Hayden, including those published by
Firehouse
magazine, April 2002, and conducted by the FDNY, as well as their statements as captured in footage shot by the Naudet brothers.

Few departments equal the rigor of New York City’s:
A Naval War College study, conducted two months after September 11, 2001, concluded: “As a function of command and control, it was evident that the Fire Department has no formal system to evaluate problems or develop plans for multiple complex events. It was equally evident that the Fire Department has conducted very little formal planning at the operational level.” Cited in “Fatal Confusion: A Troubled Emergency Response; 9/11 Exposed Deadly Flaws in Rescue Plan,”
New York Times,
July 7, 2002, p. 1.
Though the FDNY rarely lacked for resources:
Citizens Budget Commission, “Financial and Service Indicators, 1990–2002,” available at
www.cbcny.org
, shows that expenditures for the Fire Department increased from $858.6 million in fiscal 1992 to $1.1 billion in fiscal 2002. In constant 2002 dollars, this represented an increase
of 29 percent, or $253 million. The numbers of fires in the city declined by 46 percent during that period, from 100, 429 to 54,327.
… Fire Department had also issued new handheld radios:
This synopsis of the FDNY history of using portable radios was derived from interviews with Motorola officials and with retired Chief Vincent Dunn, by Kevin Flynn, January 2002; and from Chief John T. O’Hagan,
High-Rise/Fire & Life Safety
(Saddle Brook, N.J.: Pennwell Publications, 1977).
… the new radios were pulled from service:
This debate ended when the new digital radios, reprogrammed to work in the more familiar analog mode, were redistributed to firefighters in 2003 and did not generate significant complaints.
They did not bicker:
In May 2004, a staff report from the 9/11 Commission stated that police and fire commanders did not coordinate their activities. In an interview with the
New York Times,
published July 7, 2002, Fire Commissioner Thomas Von Essen stated, “That day, the police did not hook up with the Fire Department. I don’t know why.” Former police commissioner Bernard Kerik, however, testified at a 9/11 Commission hearing that he saw a police sergeant serving as a liaison to the fire command post. No witnesses corroborate Kerik’s account. The sergeant is dead and no fire officer, including those at the command post, say that they saw
any coordination between the departments. An hour after the first plane hit, one police commander, Chief Thomas Purtell of the Emergency Service Unit, did try to make his way to the fire command post, according to an oral history by his aide, but the south tower collapsed before the chief could get there.
No one from the Fire Department:
The account is based on interviews with NYPD and FDNY officials, including commanders who were at the scene and pilots who flew that day, and conclusions reached by McKinsey and Company in its studies for New York City.
… the group was disbanded in 1994:
Communication from Michael Rogovin, former deputy counsel to Queens borough president, and representative of the Aviation Emergency Preparedness Group.
… Guy Tozzoli told a legislative hearing:
Graham Rayman, “Crash Scenario Foretold in ’93; WTC Official Wanted Plan for Jet Disaster,”
New York Newsday,
November 12, 2001, p. 6. In his 1993 testimony before a state legislative committee, Guy Tozzoli referred to a replicated plane disaster staged in the 1970s. The authors could not find newspaper accounts of such a drill. However, there was a drill similar to the one he described in November 1982.
… the city did not organize a single joint drill:
