In 1988, terrorists bombed Pan Am Flight 103 over Lockerbie, Scotland, killing all passengers on board. Congress sought to remedy security shortcomings by passing the Aviation Security Improvement Act of 1990, which, among other things, ordered the Federal Aviation Authority (FAA) to prescribe minimum training requirements and staffing levels for airport security. The FAA promulgated rules according to the informal rulemaking process. However, the FAA refused to disclose certain rules concerning training at specific airports. A public interest group called Public Citizen, Inc., along with family members of those who had died at Lockerbie, wanted to know the details of airport security. What steps should they take to obtain the information? Are they entitled to obtain it?
