Federal Aviation Administrator Randy Babbitt resigned one day after a Dec. 3 arrest for driving while intoxicated forced him to go on administrative leave.In his statement, Mr. Babbitt said, "Today I submitted my resignation to Secretary Ray LaHood and it has been accepted. Serving as FAA Administrator has been an absolute honor and the highlight of my professional career. But I am unwilling to let anything cast a shadow on the outstanding work done 24 hours a day, 7 days a week by my colleagues at the FAA. They run the finest and safest aviation system in the world and I am grateful that I had the opportunity to work alongside them. I am confident in their ability to successfully carry out all of the critical safety initiatives underway and the improvements that the FAA has planned. I also want to thank Secretary LaHood for his leadership and dedication to the safety of the traveling public."
