Around-the-clock, approximately 500 people commute to building 2050 to conduct mission essential work including maintenance, administrative duties and security. Over the last 22 years, since the final B-52 Stratofortress took flight from Fairchild, building 2050 has evolved and improved in new and innovative ways to ensure the people, equipment and assets of the air refueling mission are cared for.
