I granted the motion of the United States Transportation Security Administration (“TSA”) to intervene and to develop a procedure to filter production by the Aviation defendants to avoid making public Sensitive Security Information (“SSI”). Stipulated Protective Order Governing Access to, Handling of, and Disposition of Potential Sensitive Security Information (Mar. 21, 2007). Under TSA regulations, SSI is information that, if it were to be made public, “would continue to expose vulnerabilities.” See Order (Mar. 31, 2006).4

3 One complaint listed two members of the same family who were injured in the attacks.

4 49 C.F.R. § 1520.5 (2005) (“SSI is information obtained or developed in the conduct of security activities,
including research and development, the disclosure of which TSA has determined would (1) Constitute an
unwarranted invasion of privacy (including, but not limited to, information contained in any personnel,
medical, or similar file); (2) Reveal trade secrets or privileged or confidential information obtained from
any person; or (3) Be detrimental to the security of transportation.”).
