From the foreword of Deborah A.P. Hersman: "I am pleased to present the 2011 Annual Report to Congress for the National Transportation Safety Board (NTSB). [...] 2011 was a very productive year for the NTSB, and we are working as a team to advance our transportation safety mission with accountability, integrity and transparency. Demonstrating our commitment to accountability, we completed several major accidents reports within approximately one year of the accident date, which included a massive pipeline explosion in San Bruno, California, collision between a tour boat and barge in the Philadelphia, Pennsylvania harbor, and the airline collision in Aleknagik, Alaska. In addition to responding to accidents and issuing safety recommendations, we undertook activities to impart lessons learned from our investigations and raise awareness of emerging safety issues including distracted driving, airline safety and motorcoach safety. To that end, in 2011, we held public forums and conferences on airbags in general aviation accidents, family assistance, bus and truck safety, airline fuselage structural integrity, and public aircraft operations."
