Donald Gregg.Donald Gregg. [Source: Spartacus Educational]Vice President George H. W. Bush asks CIA agent and National Security Council official Donald Gregg to serve as his national security and foreign policy adviser. Gregg agrees, and retires from the CIA. Gregg will work closely with Bush and former CIA agent Felix Rodriguez to help put together a covert operation to supply the Nicaraguan Contras with arms, cash, and supplies.

President George H. W. Bush nominates his former foreign policy adviser, Donald Gregg, to become the US Ambassador to South Korea. Gregg is one of the architects of the Contra funding and supply program (see March 17, 1983). Gregg faces some difficulty in his Senate confirmation hearings stemming from his linchpin role in Iran-Contra, with Senator Alan Cranston (R-WY) telling him: “You told the Iran-Contra committee that you and Bush never discussed the Contras, had no expertise on the issue, no responsibility for it, and the details of Watergate-sized scandal involving NSC staff and the Edwin Wilson gang [a group of ‘rogue’ CIA agents operating in apparent conjunction with Bush] was not vice presidential. Your testimony on that point is demonstrably false. There are at least six memos from Don Gregg to George Bush regarding detailed Contra issues.” But Cranston is the only member of the committee to vote against Gregg’s confirmation.

Judd Gregg.Judd Gregg. [Source: US Congress]Laura Bush, the president’s wife, and her entourage stay in the office of Senator Judd Gregg (R-NH) as they wait for the Secret Service emergency response team to arrive and take them away from Capitol Hill. Bush and those with her in the Russell Senate Office Building headed to Gregg’s office after they learned of the attack on the Pentagon and Bush’s Secret Service agents told them to go to the basement (see (9:45 a.m.-9:50 a.m.) September 11, 2001). (Gregg’s office is on a lower floor of the building, though whether it is in the basement is unclear.)
First Lady Unable to Contact Daughters - From Gregg’s office, Bush tries calling her daughters, Barbara and Jenna, who are both at university. [Bush, 2010, pp. 200] She is unable to reach them at this time. According to journalist and author Christopher Andersen, she is told that “they had both already been hustled off to what the Secret Service called ‘secure locations.’” [Newsweek, 12/3/2001; Andersen, 2002, pp. 6]
First Lady and Senator Talk about Families - The first lady then sits with Gregg, who is a longtime Bush family friend, and, she will later recall, they talk “quietly about our families and our worries for them, and the overwhelming shock we both felt.” [New York Times, 10/4/2004; Bush, 2010, pp. 200] Senator Edward Kennedy (D-MA), who is also in Gregg’s office at this time, will recall, “We kept the television set off and simply talked for a while.” [Kennedy, 2009, pp. 492]
Reporters Cannot Travel with First Lady - Noelia Rodriguez, the first lady’s press secretary, is worried about the pool reporters who are with them. She will describe, “We put them all in a room,” but Bush’s Secret Service agents tell her, “We have to leave here and we can’t take [the pool reporters] with us.” Laurence McQuillan, of USA Today, reassures Rodriguez, telling her, “Don’t worry about us.” [National Journal, 8/31/2002] Bush remains in Gregg’s office until members of the Secret Service, including the emergency response team, collect her from there (see (Shortly After 10:00 a.m.) September 11, 2001). [Bush, 2010, pp. 200] She and her staff leave the Russell Senate Office Building at around 10:10 a.m., and are then driven to a “secure location” (see (10:10 a.m.-10:55 a.m.) September 11, 2001).

Scientists who work for the US Geological Survey watch the World Trade Center towers collapse on their television sets. “We sat at home, watched that gray-white cloud roll over Lower Manhattan, and knew damned well that the dust was going to hurt a lot of people,” Gregg Swayze, a USGS geophysicist, will later tell the St. Louis Post-Dispatch. “I knew we had the best technology in the world to determine precisely what was in that dust.” [St. Louis Post-Dispatch, 2/10/2002] Swayze and other USGS scientists quickly get to work making arrangements to use USGS and NASA equipment to determine the composition of the dust clouds (see September 12, 2001).

Roger Clark, the astrophysicist who heads the US Geological Survey (USGS)‘s portion of the AVIRIS program in Denver, contacts Robert Green, head of the AVIRIS program at NASA’s Jet Propulsion Laboratory in Pasadena. (The AVIRIS, or Airborne Visible Infrared Spectrometer, is a remote-sensing unit used by NASA to determine the chemical composition of a planet’s surface and atmosphere by analyzing the infrared signatures of minerals that are reflected from the ground and comparing them with the unique peaks and curves of the signatures of thousands of minerals and materials in the USGS database. [St. Louis Post-Dispatch, 2/10/2002] AVIRIS has been used before to scan Superfund toxic sites to map hot spots of harmful substances.) [New York Times, 9/17/2002] He asks Green for NASA permission to use the AVIRIS over New York City and parts of New Jersey to determine the chemical composition of the dust and debris resulting from the collapse of the World Trade Center. [St. Louis Post-Dispatch, 2/10/2002] NASA gives the go-ahead on September 13 (see September 13, 2001).

Robert Green, head of the AVIRIS program at NASA’s Jet Propulsion Laboratory in Pasadena, informs Roger Clark, the astrophysicist who heads the US Geological Survey (USGS)‘s portion of the AVIRIS program in Denver, that NASA will permit the USGS team to use AVIRIS in an attempt to determine the chemical composition of the dust and debris that resulted from the collapse of the World Trade Center (see September 12, 2001). The crew will mount the unit to a de Havilland Twin Otter prop plane owned by NASA, which will make several passes over the WTC and surrounding area. “The Federal Emergency Management Agency and the White House Office of Science and Technology Policy… signed off on the flight. And the Air Force [has] agreed not to shoot the Twin Otter down,” the St. Louis Post-Dispatch will later report. [St. Louis Post-Dispatch, 2/10/2002]

NASA’s de Havilland Twin Otter propeller plane makes 14 passes over the region affected by the WTC collapse. The infrared-scanning AVIRIS unit, located underneath the plane, records infrared signatures of minerals reflected from the ground (see September 12, 2001). After the flight, the data tapes are sent to NASA’s Jet Propulsion Lab in Pasadena where NASA scientists Robert Green and Frank Loiza are waiting to review the data. The tapes arrive 2 a.m. the next morning. [St. Louis Post-Dispatch, 2/10/2002]

NASA scientists, Robert Green and Frank Loiza, perform the first analysis of the AVIRIS data (see 12:00 p.m. September 16, 2001-2:00 a.m. September 17, 2001) and determine that there are a total of 34 fires burning at the World Trade Center site with temperatures ranging from 800 degrees to 1,000 degrees. They pass this and all subsequent data to the White House and other government agencies that are involved in responding to the environmental impact of the attacks.

At the White House’s request, NASA’s de Havilland Twin Otter prop plane, equipped with the AVIRIS unit (see September 12, 2001), conducts additional flights over Manhattan (see 12:00 p.m. September 16, 2001-2:00 a.m. September 17, 2001), collecting data on the chemical composition of the dust and debris that was distributed throughout the city when the World Trade Center’s twin towers collapsed.
